Security Vetting

Ed Davey Excerpts

Monday 20th April 2026 Commons Chamber

[Mr Speaker]

I call Sir Ed Davey, Leader of the Liberal Democrats.

[Ed Davey (Kingston and Surbiton) (LD)]

It is 2022 all over again. Back then, when the Prime Minister was in opposition, and when it was Boris Johnson who was accused of misleading Parliament and scapegoating senior officials, the then Leader of the Opposition could not have been clearer; he said:

“The public need to know that not all politicians are the same—that not all politicians put themselves above their country—and that honesty, integrity and accountability matter.”—[Official Report, 25 May 2022; Vol. 715, c. 298.]

He promised “change”. He promised to

“break this cycle and stop the chaos.”

He promised a Government with

“more focus on long-term strategy, not the short-term distractions that can animate Westminster.”

I am afraid that the fact that he has even had to make a statement today shows how badly he has failed—how badly he has let down the millions of people across our country who are so desperate for change.

The Prime Minister blames his officials. He says that he had “no idea”. He gives every impression of a Prime Minister in office, but not in power. The facts remain, even by his own account, that the Prime Minister appointed Peter Mandelson as ambassador to the United States even after he had been warned about his relationship with Jeffrey Epstein. The Prime Minister announced the appointment before Mandelson had been vetted, despite the clear risk to national security of putting someone unsuitable in that role. One of his top officials, just three weeks into the job, clearly believed that the Prime Minister wanted Mandelson to be appointed regardless of what the vetting process turned up. The Prime Minister has relied on the vetting process to defend his decisions, so why did he ask so few questions personally about the vetting process?

We all know the truth: the Prime Minister knew that appointing Mandelson was an enormous risk, but he decided that it was a risk worth taking—a catastrophic error of judgment. Now that has blown up in his face, the only decent thing to do is take responsibility. Back in 2022, the Prime Minister rightly accused Boris Johnson of expecting others to take the blame while he clung on. That was not acceptable then, and it is not acceptable now. I hope that the Prime Minister can at least tell the House this. We will be listening very carefully to his answer. Was he given advice by Simon Case, the then Cabinet Secretary, that the necessary security clearances should be acquired before he confirmed his choice for US ambassador? Did the Prime Minister follow that advice—yes or no?

After years of chaos under the Conservatives, we needed a Government focused on the interests of the people—the cost of living crisis, the health and care crisis, and our national security. We needed a Government with honesty, integrity and accountability. Will the Prime Minister finally accept that the only way that he can help to deliver that is by resigning?

[The Prime Minister]

I set out in my statement the full facts. In September, when the Bloomberg emails came to light, I asked the then Cabinet Secretary to review the process. He told me that the process was as it should have been, and as soon as the information about the security vetting came to light last Tuesday, I asked for the facts to be established, so that I could update Parliament.

The right hon. Gentleman asks me about the announcement before developed vetting. He has heard the evidence that I have given to the House from the former Cabinet Secretary and from the former permanent secretary. In relation to the advice from Simon Case, when I asked the former Cabinet Secretary to review the process after September 2025, he specifically addressed whether the process had been followed by referencing the Simon Case letter, and assured me that the process was the right process to have followed. In answer to his question, that was specifically looked at by Sir Chris Wormald in the review that was conducted in September last year.
