In the December 12 election, Johnson gained a Commons majority of 80, his party's largest since 1987, and in contrast, the opposition Labour suffered its worst election result since the 1930s, the BBC reported.
Speaking outside No 10 on Friday, the Prime Minister thanked lifelong Labour supporters who deserted his main rival Jeremy Corbyn's party and turned to the ruling Conservatives, saying he would fulfil his pledge to take the UK out of the European Union on January 31, 2020.
He also vowed to reintroduce his Withdrawal Agreement Bill (WAB) to Parliament before Christmas, which could happen by the end of next week.
It would see MPs begin the process of considering legislation that would pave the way for the UK to leave the EU on January 31.
Johnson was expected to announce a minor re-shuffle possibly as early as December 16.
MPs will then return to Westminster on December 17 and begin the process of swearing in, before the Queen formally opens Parliament on December 19 with "reduced ceremonial elements".
In the election, the Conservatives won a total of 365 seats in the election, while Labour finished on 203, the Scottish National Party 48, Liberal Democrats 11 and the Democratic Unionist Party eight, the BBC reported.
The Brexit Party - which triumphed in the summer's European Parliament elections - failed to win any Westminster seats.
The Conservatives swept aside Labour in its traditional heartlands in the Midlands and the north of England and picked up seats across Wales, while holding off the Liberal Democrats' challenge in many seats in the south of England.
Voter turnout overall, on a cold and damp polling day, was 67.3 per cent, which was down by 1.5 per cent on the 2017 total.
