(CNA Reporter Chen Yun-yu, London, 17th) Former British Ambassador to the US, Peter Mandelson, who was implicated in the late American sex offender Jeffrey Epstein's scandal and dismissed last September, has been revealed to have never passed his security clearance. Prime Minister Keir Starmer, who repeatedly claimed he was misled by Mandelson, is now facing a renewed political crisis.
The UK's "The Guardian," traditionally seen as close to the ruling Labour Party, was the first to reveal yesterday afternoon that Peter Mandelson failed the UK government's "developed vetting." The vetting unit recommended against appointing Mandelson as ambassador to the US, but the Foreign Office overturned this recommendation, allowing Mandelson to smoothly take office early last February.
The UK government's "developed vetting" is used to screen individuals for eligibility to hold positions requiring access to the highest national secrets. It is thorough, rigorous, detailed, and intrusive, with background checks covering financial and interpersonal history, expressed views, and even details of private life.
If the vetting unit believes the subject poses security concerns (but not enough for an outright veto), the appointing authority can choose to adopt measures to mitigate the risk, while bearing the responsibility. Although the recommendations are not mandatory, appointing authorities generally follow them. Overturning a recommendation or granting a specific "exemption" is extremely rare. Cases like Mandelson's, where the vetting unit explicitly vetoed the clearance, are exceptionally few.
The specific reasons why the vetting unit refused to approve Mandelson's security clearance remain unclear. However, according to documents related to Mandelson's appointment released by the UK government in March at parliament's request, the Cabinet Office warned in a due diligence report that Mandelson's suspiciously close friendship with Epstein, as well as his business interests in China and Russia, were sufficient to pose a "reputational risk" to the UK government.
The "due diligence" was conducted before Keir Starmer officially appointed Mandelson as Ambassador to the US on December 20, 2024. This means that despite receiving warnings about Mandelson posing a "reputational risk," Starmer still decided to let Mandelson take on the crucial role.
Furthermore, internal government documents released in March revealed that shortly after Mandelson's appointment was announced, the Foreign Office quickly arranged classified briefings for him, even though he had not yet passed the developed vetting at the time.
According to reports, the security vetting unit made its decision on January 28 last year that due to the high risks, Mandelson should not be authorized to access high-level secrets. Yet, just two days later, on January 30 last year, the Foreign Office informed Mandelson that his security clearance authorization had been "confirmed."
These reports have caused an uproar in the UK. The storm continues today, and it is expected that even if Starmer personally explains and takes questions in parliament next week as planned, it will be hard to calm things down quickly.
In late February this year, Mandelson was arrested and interrogated by police on suspicion of committing the offense of "misconduct in public office" (carrying a maximum sentence of life imprisonment) because he allegedly shared sensitive government information with Epstein. At that time, Starmer was already under pressure to resign.
With local elections coming up in early May in the UK, and domestic/international challenges like the Middle East war, Ukraine war, and fiscal pressures, it remains to be seen how long Labour MPs will support Starmer as the party and national leader "for the greater good."
The Conservative Party, the largest opposition party in the UK parliament, successfully pushed a motion in early February requiring the government to release "all" internal documents related to Mandelson's ambassadorial appointment, including message logs on apps like WhatsApp. The UK government promised to comply.
According to reports, the Cabinet Office only "shockingly discovered" this week that Mandelson never passed the security clearance when reviewing the new wave of documents about to be released to parliament.
Starmer was reportedly informed of the matter on the evening of the 14th and expressed "fury." David Lammy, then Foreign Secretary and current Justice Secretary, claimed he only learned about the situation yesterday.
Olly Robbins, the Permanent Under-Secretary at the Foreign Office who was in charge of Mandelson's appointment at the time and served as his contact window after he went to the US, was urgently dismissed last night by Starmer and current Foreign Secretary Yvette Cooper.
The Permanent Under-Secretary is the highest-ranking permanent civil servant in the UK Foreign Office (the Foreign Secretary is a political appointee). Robbins only took office in early January last year, and Starmer had already announced Mandelson as Ambassador to the US two weeks prior.
According to a statement from 10 Downing Street last night, Starmer and cabinet officials did not know Mandelson failed the security clearance until this week, pointing out that the Foreign Office should take responsibility.
However, considering the sensitivity and importance of the Ambassador to the US role, various sectors in the UK question whether Robbins, as a civil servant, would likely decide to overturn the vetting unit's recommendation on his own. Moreover, it is unlikely that Robbins would fail to remind Starmer to correct his statements after Starmer repeatedly told parliament and the media that Mandelson had indeed "completed the security clearance process."
Mandelson was the UK's first political appointee as Ambassador to the US in nearly 50 years, and a senior Labour figure. By convention, political appointments require the appointer to bear greater political responsibility.
Starmer is now accused of misleading the public and parliament regarding whether Mandelson passed the necessary security checks. According to the UK's ministerial code of conduct, a minister who misleads parliament must resign to take responsibility.
However, the code also states that misleading refers to a minister "knowingly" providing false information to parliament. Whether Starmer "knew" is bound to become the key battleground in the political arena.
Darren Jones, Chief Secretary to the Treasury, stated in a media interview this morning that the Foreign Office did not inform Starmer that "Mandelson failed the security clearance," nor did they inform him that the vetting unit's recommendation was overturned. Starmer only learned of this on the evening of the 14th through documents compiled by the Cabinet Office.
Jones emphasized that besides the professionals responsible for the vetting, no official can read security clearance-related documents because such vetting often involves highly sensitive material.
