Prime Minister Keir Starmer will deliver a high-stakes statement to MPs on Monday as he seeks to contain the fallout from the Peter Mandelson vetting scandal, which has raised questions about his leadership. The controversy centres on how Mandelson became UK ambassador to the US despite the Foreign Office overruling a decision to fail his security vetting.
Starmer has said he was not informed about the vetting failure, calling it 'unforgivable' that the Foreign Office failed to tell him after he assured Parliament that due process had been followed. Downing Street has published a document arguing that no law prevented civil servants from flagging security vetting recommendations to ministers.
The scandal, first reported by the Guardian, led to the sacking of Foreign Office top civil servant Olly Robbins, who is expected to appear before MPs on Tuesday. Robbins is reportedly taking legal advice and feels unfairly treated by the prime minister.
Senior government figures fear this week could be make-or-break for Starmer, despite his handling of the Iran crisis. Deputy Prime Minister David Lammy has dismissed talk of a leadership contest, saying voters want stability, not internal party conflict.
Labour MPs had previously speculated about a leadership challenge after expected poor local election results on 7 May, but such talk has recently subsided. Lammy warned that ousting a leader over local results could trigger calls for a general election.
