Former attorney general Dominic Grieve among those criticising politicians for risking contempt of court

Disputed or debunked claims about migration and crime in the UK

Conservative and Reform UK politicians are fuelling “hysteria and anger” over immigration, with criminal trials put at risk of collapse, former ministers and police have warned.

Protests outside hotels housing asylum seekers have spread across the country in recent weeks, while debate about immigration – including instances of misinformation – has intensified.

At a Reform press conference on Monday, a man awaiting trial was referred to as “the criminal” by a Reform council leader despite not yet being convicted of any crime. Questioned on whether contempt laws had been broken, the party’s leader, Nigel Farage, said it was “good” that the council leader had become “slightly emotional”.
