JP Morgan is quietly unwinding part of its post-Brexit Parisian build-up, shifting a clutch of trading roles back to London in what insiders describe as a recalibration rather than a retreat from the Continent.

The Wall Street giant, which moved aggressively to bulk up its French operations after Britain’s departure from the European Union, has concluded that it overshot when estimating how many EU-based staff it would need to satisfy the bloc’s regulators. A handful of traders are now packing their bags for the City, with the bank citing a combination of evolving role requirements, regulatory clarity and, tellingly, personal tax considerations among bankers themselves. Bloomberg was first to report the move.

“Paris is the home of JP Morgan’s EU sales and trading team, and we are committed to our sizeable operations on the Continent for the long term,” a spokesperson for the bank insisted, in language designed to soothe the Élysée as much as the markets.

Britain’s exit from the EU triggered one of the most disruptive structural overhauls global banking has seen in a generation. Lenders were forced to redistribute assets, capital and personnel across jurisdictions to keep client access alive and regulators on side. JP Morgan was among the most enthusiastic movers, transplanting hundreds of bankers across the Channel and turning Paris into a genuine European trading hub.

The strategy paid handsome dividends, at least diplomatically. Chief executive Jamie Dimon, widely regarded as the world’s most influential banker, was awarded France’s Légion d’Honneur in recognition of the bank’s contribution to lifting the French capital’s status in international finance. By the back end of last year, JP Morgan had roughly 1,000 staff in France, with 650 of them on the markets side.

That figure is now drifting in the opposite direction, and the timing is no coincidence. The bank is pressing ahead with plans for a colossal 3m sq ft tower in Canary Wharf, unveiled in the wake of an Autumn Budget that, to the relief of the Square Mile, spared the banking sector from a long-trailed tax raid. Chancellor Rachel Reeves hailed the project as “a multi-billion pound vote of confidence in the UK economy”.

The numbers are eye-watering even by the standards of British infrastructure spending. The development is expected to pump as much as £10bn into the wider economy, generate 7,800 construction and supply-chain jobs and ultimately house up to 12,000 employees, cementing London as JP Morgan’s principal base across Europe, the Middle East and Africa.

But the deal is not done. JP Morgan has made plain that the skyscraper will only rise if Westminster keeps the fiscal weather favourable. A report from Tower Hamlets council disclosed that the bank has lobbied for “a business rates incentive over a period of years”, and ministers themselves have cautioned the local authority that JP Morgan is “unlikely to progress” without “clarity and certainty” on its eventual tax bill.

For SME owners watching from the sidelines, the message is mixed. A reinvigorated London financial centre would be a fillip for professional services firms, suppliers and the wider hospitality and property ecosystems that depend on a thriving Square Mile. Yet the unmistakable subtext, that even the bluest of blue-chip lenders are willing to play hardball on tax — is a reminder that the post-Brexit settlement remains a work in progress, and that footloose capital will continue to test the limits of British competitiveness.

The Gaydon-based luxury marque is pressing ahead with trademark action against the Chinese conglomerate that owns a sizeable slice of its share register, in a dispute that underscores the delicate politics of cross-border automotive investment.

Aston Martin Lagonda has launched legal proceedings against Zhejiang Geely Holding Group, the Hangzhou-headquartered motor group that holds a 17 per cent stake in the British carmaker, over a winged emblem the luxury marque claims is too close for comfort to its own storied badge.

The case, which pits Britain’s most famous sports car manufacturer against one of its largest shareholders, centres on a logo Geely intends to roll out on vehicles produced by its London EV Company (LEVC) subsidiary, the Coventry-based maker of the capital’s black cabs. The design features a horse’s head set within a pair of outstretched wings, and Aston Martin contends that the overall impression sails far too close to the slender winged motif that has adorned its bonnets since 1927.

The row is not a new one, Aston Martin first raised objections in 2022, when Geely sought to register the marks with the UK Intellectual Property Office. The Gaydon firm formally opposed the application the following year, arguing infringement, only for the hearing officer to side with the Chinese group on the basis that consumers were unlikely to mistake an electric taxi for a £150,000-plus grand tourer.

That ruling did little to cool tempers at Aston Martin, and the latest legal salvo suggests the board is prepared to press the point despite the awkward shareholder dynamic. Geely acquired its 17 per cent holding for roughly $310m (£245m) in 2023, making it one of the marque’s most significant backers alongside executive chairman Lawrence Stroll’s Yew Tree consortium and Saudi Arabia’s Public Investment Fund.

For Geely, the London taxi business is a strategically important British asset. The group has been quietly assembling a portfolio of UK marques over the past decade, with Lotus now firmly in its stable alongside LEVC. Its involvement at Aston Martin was initially welcomed as a source of both capital and potential manufacturing expertise at a moment when the British firm has been burning through cash to fund its electrification programme.

The dispute also comes at a bruising time for Aston Martin’s brand stewardship. The company recently saw 007 defect to the silver screen behind the wheel of a BYD, a coup for the rival Chinese electric-vehicle maker and a blow to a marque whose cultural cachet has long been bound up with the James Bond franchise.

In public, both parties are playing down the significance of the row. Aston Martin has declined to comment further on live proceedings, while Geely has characterised the matter as a routine trademark dispute and insisted it remains committed to a professional working relationship with the Gaydon marque as both business partner and investor.

Trademark lawyers watching the case note that the outcome will hinge on whether the courts accept that the average buyer, whether of an Aston Martin DB12 or an LEVC electric cab, could be confused or whether Aston’s goodwill in the wings motif is being unfairly exploited. What is already clear is that having a Chinese partner on the share register is no guarantee of a quiet life in the intellectual property courts.

A powerful new artificial intelligence model developed by Anthropic has triggered a flurry of crisis meetings among finance ministers, central bankers and senior financiers, who fear the technology could be turned on the global financial system with devastating consequences.

The model, known as Claude Mythos, has been shown to pinpoint vulnerabilities in many of the world’s most widely used operating systems, prompting alarm at the highest levels of government and commerce. While some specialists believe it marks a step-change in AI’s ability to uncover and exploit cyber-security flaws, others have urged caution, arguing that far more independent testing is needed before its true capabilities can be judged.

Canada’s Finance Minister, François-Philippe Champagne, confirmed to media that Mythos had dominated discussions at this week’s International Monetary Fund meetings in Washington DC. “Certainly it is serious enough to warrant the attention of all the finance ministers,” he said. Drawing a comparison with geopolitical risks, he added: “The difference is that the Strait of Hormuz – we know where it is and we know how large it is… the issue that we’re facing with Anthropic is that it’s the unknown, unknown. This is requiring a lot of attention so that we have safeguards, and we have processes in place to make sure that we ensure the resiliency of our financial systems.”

Mythos is among the latest additions to Anthropic’s Claude family of models, which competes directly with OpenAI’s ChatGPT and Google’s Gemini. It was unveiled earlier this month by developers responsible for stress-testing so-called “misaligned” AI behaviour, instances in which a model acts against human values or intended goals. Their verdict was that Mythos is “strikingly capable at computer security tasks”.

Citing concerns that the model could surface long-dormant software bugs or identify novel ways to exploit system weaknesses, Anthropic has opted not to release it publicly. Instead, access has been granted to a handful of technology giants, including Amazon Web Services, CrowdStrike, Microsoft and Nvidia, under an initiative dubbed Project Glasswing, which the company describes as an “effort to secure the world’s most critical software”.

On Thursday, Anthropic released an upgraded version of its existing Claude Opus model, saying this would enable Mythos’s cyber capabilities to be evaluated within less powerful systems.

Not everyone in the cyber-security community is convinced the fears are proportionate, particularly given the limited independent testing conducted so far. The UK’s AI Security Institute, which has been given access to a preview version, is the only body to have published an independent assessment. Its researchers concluded that while Mythos Preview could compromise systems with weak defences, it was not dramatically more capable than its predecessor, Opus 4. “Our testing shows that Mythos Preview can exploit systems with weak security posture, and it is likely that more models with these capabilities will be developed,” the report’s authors wrote.

Sceptics have also pointed to precedent: in February 2019, OpenAI similarly delayed the release of GPT-2 on safety grounds, a decision critics at the time dismissed as a marketing device.

Senior bankers are now to be granted early access to Mythos so they can probe their own defences ahead of any wider release. C.S. Venkatakrishnan, chief executive of Barclays, told the BBC: “It’s serious enough that people have to worry. We have to understand it better, and we have to understand the vulnerabilities that are being exposed and fix them quickly.” He added that a far more interconnected financial system had created both fresh opportunities and fresh exposures, cautioning: “This is what the new world is going to be.”

For Britain’s small and medium-sized businesses, which rely on the integrity of banking, payment and cloud infrastructure every day, the implications are considerable. A cyber incident capable of destabilising a major lender or payment processor could ripple rapidly through SME supply chains, hitting cash flow, invoicing and customer confidence within hours.

Anthropic has already flagged that Mythos has uncovered multiple vulnerabilities in core operating systems, financial platforms and web browsers. Governments and banks are being offered advance access to harden their defences before any public launch.

Andrew Bailey, Governor of the Bank of England, has said that the development must be treated with the utmost seriousness. “We are having to look very carefully now what this latest AI development could mean for the risk of cyber crime,” he said. “The consequence could be that there is a development of AI, of modelling, which makes it easier to detect existing vulnerabilities in sort of core IT systems, and then obviously cyber criminals, the bad actors, could seek to exploit them.”

The US Treasury has confirmed that it has raised the matter directly with major American banks, urging them to run internal tests ahead of any public release. Industry sources further suggest that a rival US AI firm could shortly unveil a similarly potent model, but without comparable guardrails.

For the UK technology sector, the controversy may prove an opening as much as a threat. James Wise, a partner at Balderton Capital and chair of the newly established Sovereign AI unit, a £500m government-backed venture capital fund targeting home-grown AI businesses, argued that Mythos is merely “the first of what will be many more powerful models” capable of exposing systemic weaknesses.

Speaking to the BBC’s Today programme, he said his unit was “investing in British AI companies that are tackling that, companies working in AI security and safety”, adding: “We hope the models that expose vulnerabilities are also the models which will fix them.”

For the country’s AI scale-ups and cyber-security start-ups, the message from Threadneedle Street and Washington alike is unmistakable: the defensive side of the AI arms race has just become one of the most commercially significant frontiers in British enterprise.

Rolls-Royce Motor Cars has reasserted its electric credentials with the unveiling of a £3 million zero-emissions hypercar aimed squarely at the world’s wealthiest collectors, signalling that the Goodwood-based marque intends to chase margin rather than volume in the years ahead.

The Nightingale, revealed this week, arrives only weeks after the BMW-owned manufacturer quietly abandoned its pledge to become an all-electric carmaker by 2030, conceding that a significant slice of its clientele remained unconvinced by battery power. For a company whose model names have long drawn on the darker hours, Phantom, Wraith, Ghost and Spectre, the Nightingale represents a deliberate tonal shift, named after Le Rossignol, the Cote d’Azur retreat of co-founder Sir Henry Royce.

Just 100 examples will be built, with first deliveries scheduled for 2028. Rolls-Royce is making no pretence of openness: the customer list is “by invitation only”, targeting the sort of ultra-high-net-worth individuals who already have several Rollers parked at their various residences.

The strategic logic is straightforward. Rolls-Royce has long been uneasy about its 6,000-unit annual production ceiling, fearing that volume erodes exclusivity. Rather than push the dial higher, the company has been quietly fattening its margins through ever more elaborate personalisation, bespoke starlight headliners, £26,000 onboard chessboards and £22,000 luggage sets are now routine add-ons. The Nightingale takes that logic to its natural conclusion by reviving full coach-building, allowing clients a direct hand in shaping the bodywork atop the chassis.

Nearly six metres in length and roughly Phantom-sized, the Nightingale retains the signature Pantheon grille before tapering into a torpedo-shaped rear behind a two-seat drophead cockpit. The design nods to the experimental 16EX and 17EX prototypes that Royce was developing in the 1920s after the death of his partner Charles Rolls, channelling an Art Deco sensibility into a segment , the open-top sports car, in which Rolls-Royce has historically felt somewhat awkward.

Demand for one-off commissions, notably the Boat Tail reportedly acquired by Jay-Z and Beyoncé for around $30 million, has prompted Rolls-Royce to nearly double the footprint of its Sussex plant to 100,000 square metres at a cost of £300 million. Crucially, the expansion is not designed to lift output but to house the specialist componentry and accessory capacity that underpins the bespoke model, a business in which some owners spend almost as much on extras as on the car itself.

Chris Brownridge, chief executive, framed the launch as a response to client appetite rather than a shift in strategy. “Some of the most discerning Rolls-Royce clients in the world asked us for our most ambitious work,” he said, pointing to the combination of coach-building freedom, near-silent electric propulsion and open-top motoring as the project’s defining trio.

For Britain’s flagship luxury carmaker, the Nightingale is less a statement about electrification than a declaration of where the profits now lie: in the pockets of a few hundred collectors, not the showrooms of the merely wealthy.

Britain’s solar sector delivered a statement of intent this week, smashing generation records on back-to-back days as ministers gave the green light to the country’s biggest solar installation.

Solar farms across England, Wales and Scotland produced 14.1GW of electricity at midday on Monday, eclipsing the previous benchmark of 14GW set last July. That mark lasted barely 24 hours before Tuesday afternoon’s output pushed the bar to 14.4GW.

The milestones landed on the same day the government confirmed approval for Springwell, a vast solar farm in Lincolnshire expected to generate enough power for roughly 180,000 homes at peak capacity. Energy minister Michael Shanks framed the decision as central to shielding consumers and businesses from volatile international fossil fuel markets, calling solar “one of the cheapest forms of power available.”

Springwell follows the approval of Tillbridge, another large-scale Lincolnshire installation backed six months earlier,  a notable doubling down in a county where Reform UK’s anti-renewables stance has been gaining traction. Together with 23 other major clean energy projects approved since Labour took office in 2024, the pipeline could supply the equivalent of up to 12.5 million homes.

The solar records come barely a fortnight after wind generation hit its own new peak of 23.9GW, pushing gas-fired output to a two-year low and providing a dry run for the government’s ambition of a virtually carbon-free grid by 2030. The electricity system operator is understood to be preparing to run the network without any gas generation for short spells as early as this summer.

For the thousands of smaller firms watching their energy costs with understandable anxiety, the direction of travel matters. The government has streamlined planning for so-called plug-in solar installations and updated building standards to require solar panels on all new homes from 2028, measures that should, in time, ease the burden on businesses operating from newer commercial and mixed-use premises.

Whether the pace of deployment proves fast enough to deliver the bill reductions ministers are promising remains the critical question. But with records tumbling and consents flowing, the trajectory is difficult to argue with.
