UK Prime Minister Keir Starmer is under pressure to resign following a security scandal involving Britain's former US ambassador to the US, Peter Mandelson, who had failed security vetting but was still handed the position. This comes after Starmer's party faced criticism over their performance in local elections and regional votes. Opposition politicians accuse Starmer of misleading parliament about Mandelson's background and claim that he was unaware of the issue. Downing Street has sacked the Foreign Office’s top official, Olly Robbins, amid the scandal. The scandal has raised questions about Starmer and his ability to govern, coming ahead of an expected backlash for his party in the upcoming local elections.
