Sir Keir Starmers premiership is under growing pressure from Labour MPs, angry at his decision to approve the appointment of Peter Mandelson to the role of British ambassador to Washington despite knowing about his links to Jeffrey Epstein.
Sir Keir admitted at Prime Ministers Questions that he knew about Mandelsons ongoing friendship with the convicted paedophile when he appointed him, but said that the peer lied repeatedly about the extent of the relationship.
Downing Street then tried to control the release of potentially explosive documents, which provide insight into how the decision was made.
But in the face of a mutiny from Labour MPs - led by ex-deputy PM Angela Rayner - the Government had to back down and cede control to Parliaments Intelligence and Security Committee to decide what could be released into the public domain.
Sir Keir will make a bid to focus attention on the grievance he will accuse rival political parties of peddling in a speech today, before a crunch by-election in Manchester and Mays local and devolved parliamentary elections.
