THE prime minister brushed aside his family’s divisions over Brexit — as he revealed his mother voted Leave.
Mr Johnson praised 77-year-old Charlotte Johnson Wahl as he told the conference that she backed him.
He said: ‘I am going to quote that supreme authority in my family, my mother. I know there are some keen students of the alleged divisions in my family on matters of the EU.
‘Well I want you to know, conference, that I have kept my ace up my sleeve — my mother voted Leave.’
Mr Johnson’s revelation came as a shock to his father Stanley, sitting next to his girlfriend Carrie Symonds. He was caught on camera laughing and telling her: ‘I didn’t know that!’
Mr Johnson’s parents divorced in 1979 and Ms Wahl has kept out of the limelight since. But in a rare interview in 2015, she told the Radio Times she welcomed Jeremy Corbyn’s election as Labour leader, saying: ‘Part of me is thrilled, because it’s back to the politics I remember when I was young. But he ought to do away with his beard — it makes him look like an old wizard.’
Brexit has split the Johnson family. The PM’s brother, Jo, quit his ministerial post in protest over Mr Johnson’s Brexit strategy, and sister Rachel campaigned for Remain. Dad Stanley backed Remain in the 2016 referendum, but later changed his mind.
