Someone, it seems, decided the Prime Minister didn’t need to know. And that decision has now exploded into one of the more uncomfortable political rows of Keir Starmer’s tenure.
Starmer told the Commons on Wednesday that he was deliberately kept in the dark about Peter Mandelson’s security vetting result before appointing him as Britain’s ambassador to Washington. The implication is stark: officials within the system withheld information from an elected Prime Minister about one of his own nominees.
“If I had known he had failed security vetting, I would not have appointed him,” Starmer told MPs, in what has to rank as one of the more blunt admissions of a political misstep you’ll hear at the despatch box.
Mandelson, the veteran Labour peer and former EU trade commissioner, took up the Washington post in January. His appointment was already eyebrow-raising given his reported close ties to Chinese business figures, but the revelation that he didn’t pass standard vetting procedures adds a far more serious dimension to the story.
It raises an obvious and uncomfortable question: who knew, and when? The vetting process exists precisely so that decision-makers, including prime ministers, can make informed choices. If that information was filtered out before reaching Starmer, the failure lies somewhere in the chain between the vetting agencies and No. 10.
Opposition MPs were predictably unsparing. Rishi Sunak pressed Starmer on whether he had yet established exactly which officials were responsible and what action, if any, would follow. Starmer confirmed a review is under way, though he stopped short of naming names or setting a deadline.
Mandelson himself has not publicly addressed the vetting question directly. His office has pointed to his decades of public service and his track record on transatlantic relations as justification for the role.
For now, Mandelson remains in post in Washington, continuing his work at a particularly sensitive moment in UK-US trade negotiations. Whether that situation holds depends largely on what the review uncovers and how much political pressure builds in the coming days.
The bigger question, though, is whether this is a one-off administrative failure or a sign of something more systemic in how sensitive personnel decisions actually reach the people who are supposed to make them.
