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.

Angela Rayner challenged the PM over the Mandelson affair, prompting a rapid reversal after Labour MPs rebelled. No 10 moved to distance itself and ordered a review into contacts and lobbying. The episode has raised doubts about the PM’s authority and party discipline.
