British Prime Minister Keir Starmer's director of communications Tim Allan has resigned, a day after Starmer's top aide Morgan McSweeney quit over his role in backing Peter Mandelson over his known links to Jeffrey Epstein.
The loss of two senior aides in quick succession comes as Starmer tries to draw a line under the crisis in his government resulting from his appointment of Mandelson as ambassador to the US.
"I have decided to stand down to allow a new No 10 team to be built. I wish the PM and his team every success," Allan said in a brief statement.
Allan is the fourth communications chief to leave No 10 Downing Street in less than a year, and served in the post for five months.
Allan served as an adviser to Tony Blair from 1992 to 1998 and went on to found and lead one of Britain's foremost public affairs consultancies in 2001. In September 2025, he was appointed executive director of communications at Downing Street.
