Sir Keir Starmer has confirmed conversations took place about a potential diplomatic role for his senior aide Matthew Doyle.
The ex-communications chief was made a Labour peer after leaving Downing Street in March 2025, but was suspended from the parliamentary party this February over links with a convicted sex offender.
The allegation was raised by Sir Olly Robbins as he gave evidence to the Foreign Affairs Committee on Tuesday, after he was sacked by Sir Keir last week in the ongoing row about Lord Mandelson's appointment as US ambassador.
On Tuesday, Lord Doyle said he had never sought such a position, and was not aware of anyone speaking to the Foreign Office about finding a role for him.
At PMQs, the prime minister was questioned by Lib Dem leader Sir Ed Davey, and Conservative MP Mike Wood, whether Downing Street had considered appointing Doyle to a diplomatic position.
