British MPs will vote before Christmas on the Brexit deal that Prime Minister Boris Johnson agreed with the EU, Johnson says.
"We're going to get Brexit done," Johnson told supporters in Sedgefield in northeast England, where the Conservatives made a historic gain from the opposition Labour Party in Thursday's snap election.
"What kind of (Brexit) deal have we got?" he asked the crowd.
"Oven ready!" chanted his supporters in the constituency, once held by former Labour prime minister Tony Blair.
"We have 100 per cent support (for the deal from Conservative MPs)," Johnson said.
"We can definitely get it in before Christmas."
Passage of the deal, which allows Britain to withdraw from the EU on January 31, is expected to be a formality after the Conservatives won a big majority in the election.
Johnson called the poll in a bid to break a parliamentary impasse over Brexit.
On Saturday, he promised to build "a one-nation Conservative government, a people's government" that will increase funding for health services, policing and infrastructure.
Thursday's election has "changed the future of our country", Johnson said.
The Conservatives won 365 seats in the 650-seat parliament, from 43.6 per cent of votes under Britain's constituency-based, winner-takes-all electoral system.
Labour lost 59 seats to end the election with 203 MPs.
The anti-Brexit Liberal Democrats also lost ground despite recruiting several high-profile pro-EU MPs from the Conservatives and Labour.
Left-wing Labour leader Jeremy Corbyn and Liberal Democrat leader Jo Swinson both said they plan to step down.
