Boris Johnson reveals how his mother voted on Brexit in speech at Tory party conference

Boris Johnson has revealed that at least one member of his family supports his Brexit stance – his mum.

Addressing recent criticism from his siblings – his brother Jo Johnson and sister Rachel Johnson – Mr Johnson told Conservative Party members that he at least had the support of his mother.

The PM said: “I want you to know, conference, I have kept my ace up my sleeve. My mother voted Leave.”

He added: “My mother taught me to believe strongly in the equal importance, the equal dignity, the equal worth of every human being on the planet."

Mr Johnson’s relationship with his family has been questioned in recent weeks.

Jo Johnson resigned from his brother’s Cabinet because he disagreed with him over Brexit, and Rachel Johnson has suggested that the PM had been influenced by billionaires who wanted to make money out of a no-deal Brexit. Boris Johnson has denied this.

Writer Ms Johnson was also unhappy with the PM’s comments in the House of Commons last week when he mentioned the murdered MP Jo Cox.

But she reacted positively to her brother mentioning their mother at the conference and confirmed in a tweet that the PM was telling the truth about her vote.

Boris Johnson said this week he would worry about spending Christmas with his family after the country had left the EU on 31 October.

In the rest of his keynote speech the PM urged Brussels to compromise as he put forward “constructive and reasonable proposals” to resolve the Brexit deadlock.

He insisted the UK was ready to leave without a deal on 31 Octobe if the European Union refused to work with him on reaching an agreement.

Mr Johnson said his plan to replace the Irish backstop would “in no circumstances” result in checks at or near the border in Northern Ireland.

He added: “Today in Brussels we are tabling what I believe are constructive and reasonable proposals which provide a compromise for both sides.

“And at the same time we will allow the UK – whole and entire – to withdraw from the EU, with control of our own trade policy from the start. ”
