Steve Barclay has been named the new Health Secretary, Whitehall sources told PA, after Boris Johnson was forced to appoint his own Chief of Staff to the top job.
Mr Barclay was already doing two jobs, also serving as a Cabinet Office minister, but he was moved tonight after Sajid Javid and Chancellor Rishi Sunak resigned.
Mr Johnson held crisis talks with aides after the two resignations just nine minutes apart - which sources claimed were not co-ordinated.
