Peter Mandelson: Government Appointment

Ian Sollom Excerpts

Tuesday 21st April 2026 Commons Chamber

[Ian Sollom (St Neots and Mid Cambridgeshire) (LD)]

Yesterday the Prime Minister stood at the Dispatch Box for nearly 2.5 hours and said on at least 12 occasions that appointing Mandelson was an “error of judgment”—his judgment. He apologised and said that he took responsibility for it, but at no point—not once in that 2.5 hours—did he tell the House what his error of judgment was or exactly where he went wrong in his reasoning. That distinction matters. Saying, “I should not have appointed him,” is a description of an outcome; it is not an account of a judgment. It is like saying, “I should not have crashed the car,” without accounting for the actions that led to the crash, because whether the driver was speeding, distracted or asleep at the wheel, the answer matters. It matters for understanding what went wrong, for preventing it from happening again and for judging whether the driver should still be behind the wheel.

The difference is not a technicality; it is the difference between meaningful accountability and accountability that is merely performative, between a Prime Minister who owns his decisions and one who merely acknowledges them. Accountability to this House is not a constitutional nicety; it is the condition on which this House and the people we all represent grant the Government the authority to act at all.

We all know what was in the due diligence report that the Prime Minister received in December 2024: the twice-resigned Minister, the China and Russia connections, and the Epstein association that continued after conviction. The Prime Minister received that report. He has confirmed that he knew its contents, but he proceeded anyway. That was his judgment, and it is that judgment—not the vetting process, not the Foreign Office chain of command, not Sir Olly Robbins—that this House has not been given an account of. Instead, yesterday we received a detailed, exhaustive account of what officials failed to tell him. Yet the more exhaustive the catalogue of official failures becomes, the more completely the Prime Minister’s own reasoning disappears from view. He cannot simultaneously claim an error of judgment and outsource its explanation to official failure. He has offered us an alibi instead of an explanation, an account that places him away from the scene of the crash. Yesterday’s statement was a masterclass in process—process that the Prime Minister was apparently unaware of. It was not an account of a judgment.

This morning, Sir Olly Robbins told the Foreign Affairs Committee that No. 10 showed no interest in whether Mandelson would receive clearance, only when, that there was, in his words, a “generally dismissive attitude” to Mandelson’s vetting, with focus only on getting him to Washington “quickly”. This is not a picture of a Prime Minister kept in the dark by officials. The alibi, it turns out, has witnesses, and they are not saying what the Prime Minister told us yesterday.

The Prime Minister has wide Executive latitude. He is entitled to make difficult appointments and to weigh competing considerations and reach conclusions that others would not reach. That is what governing requires. But the latitude is not unconditional. It comes with a democratic obligation to account for his reasoning to this House and to the people we represent—not to describe outcomes or to catalogue process, but to explain his judgment. What did the Prime Minister weigh up, what did he conclude and where in his reasoning did he think he went wrong?

Yesterday the Prime Minister told us 12 times that he made an error of judgment, but he has not told us once what that error actually was. We still do not know how he crashed that car, and this House demands an answer.
