When a prime minister uses the word “staggering” to describe their own government’s actions, you know something has gone seriously wrong.
Keir Starmer is under mounting pressure to explain how Peter Mandelson came to be appointed US Ambassador despite reportedly failing to clear the government’s security vetting process. The revelation has triggered fresh calls from opposition MPs for the PM to step down, with some describing it as a fundamental breach of national security protocol.
Starmer insists he was never informed that Mandelson had not passed the necessary checks before the appointment was confirmed. “I was not told,” he said, calling the situation “staggering”. It’s a defence that raises its own uncomfortable questions: if the PM wasn’t told, then who knew, and why did the appointment go ahead anyway?
Mandelson, the veteran Labour grandee who served twice in Cabinet before being forced to resign on both occasions, is no stranger to controversy. His appointment to Washington was already seen by some as a bold, even provocative choice given his complicated political history. But a failure to pass formal vetting moves the story into altogether more serious territory.
The vetting process for senior government appointments exists precisely to protect sensitive diplomatic relationships and classified information. The US Ambassador role is one of the most consequential postings in British foreign policy, particularly given the current state of transatlantic relations.
“If the Prime Minister genuinely didn’t know, that points to a catastrophic breakdown in how appointments are managed at the very top of government,” one former senior civil servant told journalists briefed on the matter.
Downing Street has not yet clarified who in the appointment chain was aware of the vetting outcome, or whether Mandelson himself disclosed any issues to officials. Those gaps in the timeline are exactly what opposition figures are now determined to fill.
There’s also the question of what happens next. Mandelson is currently in post. Whether the government can credibly keep him there, given everything that’s now public, may well depend on what the coming days reveal about exactly how this decision was made and who signed off on it.
