Mr Cummings struck a defiant note at the regular Friday meeting of the special advisers in Downing Street last night.
He reportedly told the group that he was “p***** off’ about people briefing ‘bull****’ about spad pay and the lack of gender balance among advisers. He added: “If you don’t like how I run things, there’s the door. **** off.”
He told advisers that if they had a problem with his style they knew where the door was he said they could talk to him in private if they had concerns, The Times reported.
