Two addresses have been searched by police as part of an investigation into Peter Mandelson.
The Metropolitan Police confirmed it was carrying out search warrants at an address in Camden, London, and another in Wiltshire.
The warrants form part of an investigation into Lord Mandelson, centring on allegations of misconduct in public office, following the latest Epstein files release.
The Met is investigating the peer over accusations relating to files appearing to show that while he was business secretary following the 2008 financial crisis, he passed on market-sensitive information to paedophile financier Jeffrey Epstein.
As part of its statement on Friday, the police said no one had been arrested.
Sir Keir Starmer remains under pressure over the Lord Mandelson scandal, amid demands to release documents related to the peer’s vetting as former UK ambassador to the US.
The prime minister promised to publish documents in connection with the ex-Labour peer, but so far has not done so, after claiming the Metropolitan Police want him to hold off.

In a statement confirming the searches, deputy assistant commissioner Hayley Sewart said: “I can confirm that officers from the Met’s central specialist crime team are in the process of carrying out search warrants at two addresses, one in the Wiltshire area, and another in the Camden area.
“The searches are related to an ongoing investigation into misconduct in public office offences, involving a 72-year-old man.
“He has not been arrested and enquiries are ongoing.”
Documents coming ‘shortly’
Speaking to journalists earlier, Downing Street said the government will “publish shortly” the documents.
The prime minister’s official spokesperson said it was important that papers were made available to parliament as quickly as possible.
Sky News understands the government was working with the police to ensure any document released did not undermine the police investigation into Lord Mandelson over allegations he sent sensitive government documents to convicted sex offender Epstein.
Officials are in the early stages of assessing the documents, of which there are thousands, it is understood.
The scandal surrounding Lord Mandelson has left Sir Keir under severe pressure, with some in Labour wanting him to resign.
Even more focus has been placed on the prime minister’s chief of staff, Morgan McSweeney, who was a close political ally of Lord Mandelson.
Speaking to the BBC, Labour backbencher MP Simon Opher called for a “clear out at Number 10”.
“If my chief of staff had done this, I think he would be looking for another job,” Mr Opher said.
Veteran Labour MP Clive Efford and Southport MP Patrick Hurley have also said Mr McSweeney should leave Number 10.

Former cabinet minister and Labour grandee Harriet Harman told the Electoral Dysfunction podcast previously that the prime minister needed a “real reset” in Downing Street.
Sir Keir could lose his premiership if he does not do the right thing, Ms Harman added.
However, so far no big names on the current frontline of Labour politics have turned their fire on the prime minister and his staff.
