LONDON — Keir Starmer will draft a new law to strip Peter Mandelson of his right to sit in Britain’s House of Lords after new revelations about the former British ambassador to Washington’s links to convicted sex offender Jeffrey Epstein appeared in the Epstein files.

The British prime minister has asked officials to draft legislation to remove Mandelson from the House of Lords “as quickly as possible,” his spokesman told reporters Tuesday afternoon.

No.10 Downing Street said the Cabinet Office has also referred material to the police after the newly released files appeared to show Mandelson sharing live government policy deliberations with the disgraced financier. 

The Metropolitan Police said Monday it is reviewing allegations of misconduct in a public office.

Starmer’s spokesperson said the Epstein file documents “contain likely market sensitive information surrounding the 2008 financial crash and official activities thereafter to stabilize the economy.”

“Only people operating in an official capacity had access to this information, [with] strict handling conditions to ensure it was not available to anyone who could potentially benefit from it financially,” the spokesperson said, adding: “It appears these safeguards were compromised.”

Mandelson, a former Labour Cabinet minister who twice had to resign from Tony Blair’s government, was given a seat in the House of Lords by Gordon Brown in 2008 — a move which allowed Brown to appoint him as business secretary.

More recently, the peer was made U.S. ambassador by Starmer as he sought to build strong ties with Donald Trump’s administration. The British prime minister sacked Mandelson last year after the release of U.S. Department of Justice files which shed new light on Mandelson’s friendship with Epstein.

The former ambassador quit the ruling Labour Party on Sunday— but Starmer is under mounting political pressure to go further.

Starmer “regards it as ridiculous that a peerage cannot be removed, except with primary legislation, something that has not happened since 1917,” his spokesman said Tuesday.

“The prime minister believes there is a broader need for the House of Lords to be able to remove transgressors more quickly,” the spokesperson added.

Downing Street has called for cross party support for its bid to modernize the unelected House of Lords. Currently peers can retire from the upper chamber — but they cannot be removed.
