Keir Starmer faces mounting pressure after opposition parties called for an inquiry into his handling of Lord Peter Mandelson’s appointment as US ambassador. Conservatives, SNP, and Liberal Democrats have urged the Speaker to refer the matter to the Privileges Committee, amid claims Parliament may have been misled over whether proper vetting procedures were followed. The controversy centres on revelations that Mandelson reportedly failed key security checks but was still appointed after Foreign Office intervention. Evidence from senior civil servant Sir Olly Robbins has contradicted earlier government statements, raising questions about what Starmer and when. Further scrutiny is expected as senior officials appear before parliamentary committees. Criticism has also emerged within Labour ranks, with some MPs voicing concern over leadership and transparency. While the Prime Minister insists due process was followed and denies wrongdoing, the situation highlights growing tensions around accountability, trust, and integrity in public office.
