Morgan McSweeney has said he made a "serious error of judgement" in advising the Prime Minister in the appointment of Lord Peter Mandelson to US Ambassador.

Speaking to the Foreign Affairs Committee, the former Chief of Staff said: "I've spent much of my working life trying in whatever role I held to make this country fairer, stronger and more successful. I have always believed public service is a privilege.

"It brings responsibility and scrutiny, but it also brings a meaningful chance to improve people's lives. That is what motivated me in Government.

"The appointment of Mandelson as ambassador was a serious error of judgement. I advised the Prime Minister in support of that appointment and I was wrong to do so."
