Boris Johnson has thanked voters in traditional Labour heartlands who voted Conservative for placing their trust in him, adding that they have "changed the political landscape".
Speaking in Sedgefield, Tony Blair's old constituency on Saturday, Mr Johnson said: "I want to thank you, all of you, for the trust that you have placed in us in the Conservative Party and in me, and I know how difficult it was, it can be to make that kind of decision.
"And I can imagine people's pencil's hovering over the ballot paper and wavering before coming down for us and the Conservatives, and I know that people may have been breaking the voting habits of generations to vote for us.
"And I want to thank the people of the North East for voting for the Conservative Party and I will repay your trust - and everything that we do, everything that I do as your Prime Minister, will be devoted to repaying that trust.
"And first of all what are we going to do? We're going to get Brexit done."
Mr Johnson said the Government would be committed to spreading opportunity across the country.
"We believe that talent is evenly distributed throughout our country but opportunity is unfairly distributed," he told supporters in Tony Blair's old Sedgefield constituency.
"We are going to rectify that as a One Nation Conservative Government, as a people's Government."
He added: "We are going to recover our national self-confidence, our mojo, our self-belief and we are going to do things differently and better as a country.
"It is going to be a wonderful, wonderful time for our country. Our country will stand tall in the world."
