Only today:
Labour has written to the cabinet secretary over what the party describes as "hugely concerning" allegations against Liz Truss's chief of staff.
Angela Rayner, the deputy leader of the opposition, wants Simon Case to investigate allegations first reported in The Sunday Times about Mark Fullbrook.
The PM's official spokesman yesterday said Mr Fulbrook had Liz Truss's "full support."
Mr Fullbrook has not travelled to New York for the UN General Assembly with the prime minister, but Number 10 insisted he was working on government business, including help for businesses with energy costs and Friday's mini budget.
Ms Rayner wrote that it was "hugely concerning to see reports over the weekend that the new Downing Street chief of staff has been interviewed by the FBI over links to an alleged plot to influence a US election. These are incredibly alarming revelations which the public will rightly want clarity on."
The FBI probe relates to allegations that financier and Tory donor Julio Herrera Velutini promised to help the former governor of Puerto Rico get re-elected if she dismissed an official investigating a bank he owned there.
