Boris Johnson’s most senior adviser Dominic Cummings is reportedly set to leave his Downing Street position by the end of the year. Mr Cummings told the BBC that “rumours of me threatening to resign are invented” after speculation that he would follow communications director Lee Cain in leaving Number 10. However, he said that his “position hasn’t changed since my January blog” when he wrote that he hoped to make himself “largely redundant” by the end of 2020.
