Vice-president and state department look to push far-right idea that mass migration is causing civilisational decline

• How Britain was rocked by Henry Nowak’s murder – and why the US intervened

In the state department of past administrations, how to respond to an incendiary event such as the murder of the British student Henry Nowak would have required deliberations, memos and meetings. Given how it has roiled the UK and inflamed tensions over migration and race, the cautious diplomats at Foggy Bottom probably would have said nothing at all.

Now they tweet from the hip. “Ideological conditioning and two-tiered policing are glaring symptoms of civilizational decline,” the department’s official account posted on Thursday. “They must be rejected across the West.”

Reform leader jeered in parliament as he is urged to condemn violence

Zia Yusuf, the Reform UK home affairs spokesperson, told Sky News this morning that he thought the treatment of Henry Nowak did justify his party’s claim that two-tier policing operates in the country. He said:

Having watched that footage [of Nowak’s arrest] … it’s hard to escape the conclusion that it is a demonstrable example of structural two-tier policing that is embedded in Hampshire police force and forces across the country.

People can go to Hampshire police’s website and read their race action plan that was brought about under a Tory government.

We understand and appreciate as police officers that we are accountable for our actions. What we ask, however, is that those actions are judged through fair and transparent processes. In this case, that process is already underway with the IOPC conducting their independent investigation.

What we, as a society, cannot accept is the violent scenes we saw in Southampton last night.

I know that since the release of the body-worn video footage from the night of Henry Nowak’s murder, there is a desire for answers and accountability but that must be done in the right way and not used as an excuse to threaten and intimidate my officers and bring violence to our streets causing fear and harm to those living and working in Hampshire and the Isle of Wight.
