Should Keir Starmer resign as Prime Minister over the Mandelson vetting scandal?

Peter Mandelson failed security vetting for his appointment as UK envoy to Washington due to concerns including links to Jeffrey Epstein, Russia, and Putin, but the Foreign Office overruled officials after Starmer announced the role. Starmer claims he was unaware of the failure, describes the lapse as unforgivable, and blames officials, while critics accuse him of misleading Parliament by stating Mandelson had clearance. Opposition leaders demand his resignation amid mounting pressure and threats to his leadership.
