Lee Cain spotted in Whitehall following resignation

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.
