Prime Minister Keir Starmer Faces Intense Scrutiny Over Lord Mandelson Vetting Failure

Prime Minister Keir Starmer is scheduled to address Members of Parliament on Monday, facing questions regarding the process that led to Lord Mandelson's appointment as ambassador to the United States, despite the peer reportedly failing initial security vetting checks.

Unanswered Questions Plague Downing Street

Mr Starmer stated this week that he was only recently informed of Lord Mandelson's failure to clear developed vetting (DV), a rigorous procedure designed to ensure individuals with access to classified information, such as ambassadors, do not pose a security risk. He described this revelation as "staggering" and "completely unacceptable." However, opposition parties, including Conservative leader Kemi Badenoch, have dismissed his explanation as "completely preposterous."

Previously, in September, a day before Lord Mandelson's dismissal, Mr Starmer assured MPs that "full due process" had been adhered to. By February, he asserted that "security vetting carried out independently by the security services... gave him clearance for the role." This timeline raises significant questions about when information was known within Downing Street and what specific inquiries were made between September and February.

Foreign Office Decisions Under Fire

United Kingdom Security Vetting (UKSV), a specialist agency within the Cabinet Office, reportedly recommended against granting Lord Mandelson security clearance. Despite this, officials within the Foreign Office proceeded with the appointment. Government guidance indicates clearances can be approved, approved with "risk management," or denied. An email disclosed by the Cabinet Office on Friday confirmed UKSV's recommendation was that clearance "should not be granted."

The decision to proceed despite UKSV's advice, and the specific individuals responsible for that decision within the Foreign Office, remain unclear. Sir Olly Robbins, the department's most senior official until his recent removal, is expected to provide testimony to the Foreign Affairs Committee on Tuesday, which may shed light on how Lord Mandelson's clearance was handled. Dame Emily Thornberry, a committee member, has suggested she was "misled" by Sir Olly in November last year.

The timing of Lord Mandelson's political appointment, announced before the Foreign Office decided to grant clearance despite vetting findings, suggests a potential reluctance to reverse course. Mr Starmer's office maintains that no ministers, including the Prime Minister, were aware of the vetting failure until this week, despite repeated requests for "assurances" from the Foreign Office.
