Keir Starmer has told his critics in the Labour party to back him or quit - and said the party is "never going back".
The Labour leader said the party was "unrecognisable" from when he took over from Jeremy Corbyn and the changes he's made are “permanent, fundamental, irrevocable”.
In a direct challenge to Mr Corbyn's backers, he said: “There are those who don’t like that change, who still refuse to see the reality of what had gone on under the previous leadership.
