Wes Streeting is accused of plotting to replace the PM after leaked messages with Lord Mandelson criticised the government’s growth strategy. He denies it. No 10 says the PM remains in charge amid Labour infighting and renewed speculation over leadership manoeuvres.

Morgan McSweeney has left No 10 after criticism of his role in the move to appoint Lord Mandelson as UK ambassador to the US. The exit, amid claims of a ‘boys’ club’ and concern over patronage, increases pressure on the PM’s judgement and process, with Labour now set to choose a successor.

Police executed warrants at Lord Mandelson’s London and Wiltshire properties during an inquiry into an alleged leak of government papers to Jeffrey Epstein. Detectives are examining potential misconduct in public office. No arrests have been disclosed.

Angela Rayner’s hopes of succeeding at No 10 face delay as HMRC examines past property dealings, including stamp duty on a former home. She insists she followed the rules, while opponents demand clarity before any leadership contest should the PM step aside.
