UK Prime Minister Sir Keir Starmer is facing a "commons showdown" over the "Mandelson vetting scandal", which could cost him his leadership. The Times reports that the former British Ambassador to the US, Lord Mandelson, had a top level of security clearance, which is likely to increase pressure on Starmer. Meanwhile, US Vice-President JD Vance is heading back to Islamabad for further negotiations with Iran, despite President Donald Trump's offer of a "reasonable deal" and a threat to bomb Iran's bridges and power plants if it does not reach an agreement. The Daily Mail declares this as the day Starmer must take responsibility for the appointment.
