UK PM Starmer faces resignation calls over envoy

UK Prime Minister Keir Starmer is set to address parliament on Monday, facing mounting calls for his resignation. The controversy stems from his handling of the appointment of senior Labour figure Peter Mandelson as U.S. ambassador, which proceeded despite Mandelson having failed a vetting process. The political fallout has created a significant crisis for Starmer's government. The situation highlights internal party tensions and questions over the government's judgment in key diplomatic postings.
