In a statement full of familiar election slogans that he was “getting Brexit done” and the deal with the EU was “oven ready”, Johnson also thanked those who do not see themselves as natural Conservatives for backing him at the polls on 12 December.

He said: “I know that many of you do not consider yourself natural Tories and may only have lent me your vote. I am humbled by your support and will work every day to keep it. I am also acutely aware that there are millions of people who did not vote for me and were disappointed by the result.

“If you are one of them, I want to reassure you that I will be a prime minister for everyone, not just those who voted for me. I know that you love this country no less, simply because you voted for another party or wanted to remain.”
