A close aide of Boris Johnson is reported to have left Downing Street in the latest blow to Vote Leave influence in the heart of government.
Reports by The Times and Sky News suggested that Oliver Lewis had quit as head of the No 10 Union Unit following tensions with new arrivals in Mr Johnson’s team.
Mr Lewis’s departure follows the removal in November of senior adviser Dominic Cummings and director of communications Lee Cain, who he worked alongside during the 2016 EU referendum campaign.
