Keir Starmer has admitted he 'deeply regrets' his warning that uncontrolled immigration risks turning Britain into an 'island of strangers'.
The PM made the jibe in a speech last month, seen as marking a tough new approach to combat the political threat posed by Reform.
But Sir Keir said he realised the language 'wasn't right' after critics claimed it had echoes of Enoch Powell's Rivers of Blood speech.
He pointed to the impact of an alleged arson attack on a property owned by his family, saying he and wife Lady Victoria had been 'really shaken up'.
The premier gave the speech on May 12, hours after the blaze.
