Lee Cain has been spotted in Whitehall following his dramatic resignation as the Prime Minister's director of communications.
He had been offered the post of chief of staff but a backlash among Tories and Mr Johnson's inner circle ultimately led him on Wednesday to announce his departure from No 10 rather than a promotion.
His exit has sparked speculation that he could be followed by Dominic Cummings, Mr Johnson's top adviser who is seen as the most powerful figure in No 10.
