Morgan McSweeney to Testify on Lord Mandelson Security Vetting to MPs Next Week
Morgan McSweeney, the Prime Minister's former chief of staff, is scheduled to give evidence to Members of Parliament on the Foreign Affairs Committee next week. His testimony will focus on his involvement in the security vetting process for Lord Mandelson, who was subsequently appointed as the UK's ambassador to the United States.
Mr McSweeney, who advised the Prime Minister on Lord Mandelson's appointment, is anticipated to face questions concerning whether undue influence was exerted on civil servants to expedite the vetting procedure. This scrutiny follows accusations by Sir Olly Robbins, a former senior Foreign Office civil servant, who described Downing Street's attitude towards the vetting as "dismissive." Downing Street has publicly denied these claims.
Cat Little, the most senior civil servant within the Cabinet Office, is also slated to appear before the committee on Thursday. Last week, Ms Little informed Sir Keir Starmer that the UK Security and Vetting (UKSV) team had raised specific concerns regarding Lord Mandelson, yet the Foreign Office proceeded to grant him security clearance regardless.
Dame Emily Thornberry, the committee chair, has confirmed that Ian Collard, the Foreign Office's Chief Property and Security Officer, and Sir Philip Barton, former top civil servant at the Foreign Office, have also been asked to provide evidence. The Prime Minister effectively dismissed Sir Olly last week, reportedly expressing anger over the Foreign Office's failure to inform him that Lord Mandelson had initially failed security vetting.
During his testimony to the Foreign Affairs Committee on Tuesday, Sir Olly stated that while he had not reviewed the UKSV documents directly, an oral briefing indicated Lord Mandelson's case was "borderline" and the associated risks could potentially be managed. He further explained that civil service guidelines precluded him from disclosing detailed vetting information to the Prime Minister, only his final decision. Sir Olly also cited an "atmosphere of pressure" within his department to complete the clearance process for Lord Mandelson's deployment to Washington.
Lord Mandelson was relieved of his duties seven months into his ambassadorship, following revelations of his past association with convicted sex offender Jeffrey Epstein. Sir Keir has faced criticism for the appointment, and in February, Mr McSweeney resigned from his Downing Street position, taking "full responsibility" for his advisory role in the Prime Minister's decision.
The controversy surrounding Lord Mandelson's vetting has reignited questions among Labour MPs regarding Sir Keir's judgement and leadership. Labour MP Jonathan Brash commented, "Ultimately, we are in a situation where I don't think anyone reasonably expects the prime minister to lead the party into the next election and I think we have to refocus this government on the priorities of the British people."
During Prime Minister's Questions, Sir Keir defended his actions, asserting that had the Foreign Office communicated the vetting concerns, "Mandelson would not have been committed to post." Conservative leader Kemi Badenoch countered, stating that Sir Olly had been "sacked for the prime minister's own failings" and that Sir Keir's own MPs "know that is not fair."
