Antonia Romeo, Keir Starmer’s most senior civil servant, has been given a powerful new mandate to deliver his priorities, while Darren Jones, the No 10 chief secretary, has shifted to a role more focused on wider Whitehall reforms.
Romeo, who was promoted last month, took over the job of cabinet secretary and head of the civil service after an unsuccessful year in charge by her predecessor, Chris Wormald, who was not considered effective enough by No 10.
