Sir branded as a "very naughty boy" during a meeting of Labour MPs tonight. The Prime Minister mocked the Reform leader over the party's civil war as he addressed the Parliamentary Labour Party.

Great Yarmouth MP Rupert Lowe was last week stripped of the whip and reported to police amid claims of threatening violence against the party chairman and office bullying allegations, which he denies. Mr Lowe had questioned "messiah" Mr Farage's leadership in a bombshell interview the day before.

An MP told GB News that Sir Keir said to the gathering: "Easter is coming up. We are in the middle of Lent.

"But Nigel Farage is not the Messiah - he's a very naughty boy."

In the interview with the Daily Mail, Mr Lowe said that Reform remained a "protest party led by the messiah" under Mr Farage.

Asked whether the former Ukip leader had the potential to become Prime Minister, as his supporters have suggested, Mr Lowe said: "It's too early to know whether Nigel will deliver the goods.

"He can only deliver if he surrounds himself with the right people."

In its statement, Reform said that an independent KC had been appointed to look into the bullying claims.
