Boris Johnson is to address his new intake of Tory MPs as they prepare to vote on his Brexit deal.
The prime minister will welcome the 109 newly elected colleagues, many of them from former Labour areas across the north and Midlands, to the House of Commons on Monday.
Mr Johnson will use his majority of 80 to get his Withdrawal Agreement Bill (WAB) to implement Brexit approved so the UK can formally leave the EU by the end of January.
The prime minister has pledged to bring the Bill back before the Commons before Christmas but it is not yet known when MPs will begin voting on it.
Ahead of the private speech, a Number 10 source said: "The seismic events on Thursday returned Conservative MPs in Bolsover, in Blythe and in Bishop Auckland to name a few.
"This election and the new generation of MPs that have resulted from Labour towns turning blue will help change our politics for the better.
"The PM has been very clear that we have a responsibility to deliver a better future for our country and that we must repay the public's trust by getting Brexit done.
"That's why the first piece of legislation new MPs will vote on will be the Withdrawal Agreement Bill."
Meanwhile, Housing Secretary Rob Jenrick confirmed the government would take a fresh look at how the BBC is paid for, amid accusations of partiality.
He said the government is to consider whether failure to pay the TV licence fee should cease to be a criminal offence but denied the move was aimed at making life difficult for the BBC.
It is expected to be an eventful week in Westminster, with a Government reshuffle on the cards and the swearing-in of MPs to begin on Tuesday.
ITV News Political Correspondent Carl Dinnen looks at the week ahead:
The Queen will formally open Parliament on Thursday when she sets out the Government's legislative programme during a slimmed-down State Opening.
The prime minister will also enshrine in law the multi-year financial commitment to the NHS - a first for any government - that will see a £33.9 billion per annum increase in the NHS budget by 2023-24.
Approving the WAB will not mean the Brexit saga is over. The UK will remain in the EU until at least the end of 2020 during the implementation period.
This time will be used by Brussels and London to hammer out a trade deal and decide on their future relationship on subjects such as security.
But EU figures have been highly sceptical this can be sorted within the year, with chief negotiator Michel Barnier saying the timetable was "unrealistic" in leaked comments.
Senior Cabinet member Michael Gove, who is the Chancellor of the Duchy of Lancaster, tried to dismiss these fears.
He told Sky's Sophy Ridge on Sunday he is "confident" the agreement could be finalised by the deadline because "quite a lot of the details" are agreed in the Political Declaration agreed with the EU.
Mr Johnson is not the only leader who will be welcoming a new intake of MPs on Monday, with the SNP's Westminster leader Ian Blackford expected to meet his new colleagues.
This will demonstrate one of the greatest problems the prime minister is expected to face - Nicola Sturgeon's party will be making intensifying demands for a fresh Scottish independence referendum.
Scotland largely voted against Brexit and the SNP increased its share of Scottish seats in the Commons to 47 out of a total of 59 in Thursday's General Election.
Another pro-independence MP, Neale Hanvey, took the Kirkcaldy and Cowdenbeath seat but is currently suspended by the party over allegations of anti-Semitism.
He will sit as an independent MP until a disciplinary process is completed.
Ms Sturgeon insisted the Tories were "raging against reality" by blocking another independence vote as she vowed to "pursue the plan I won a mandate for".
But Mr Gove said the Conservatives would "absolutely" not hold another public vote on the matter during the course of the Parliament, regardless of the result of the 2021 Holyrood election.
Labour should also have a busy week as the party seeks to replace Jeremy Corbyn as leader after suffering its worst General Election result since 1935.
