The government plans to ask MPs to vote on Boris Johnson’s Brexit bill on Friday, Downing Street has said.
The PM’s spokesman said the government planned to start the process in Parliament before Christmas in the “proper constitutional way”.
The Withdrawal Agreement Bill is the legislation that will enable Brexit to happen – the UK is due to leave the EU on 31 January.
It comes as the PM prepares to address his new MPs in Westminster.
Many of the 109 new Conservative MPs won in areas traditionally held by Labour in Thursday’s election, which saw the party gain an 80-seat majority.
Mr Johnson is also carrying out a mini cabinet reshuffle, naming Simon Hart as Welsh Secretary. It marks a big promotion for the 56-year-old MP for for Carmarthen West and South Pembrokeshire, who was previously a junior minister in the Cabinet Office.
The prime minister has also cleared a parliamentary report into alleged Russian interference in UK democracy for publication.
The Queen will formally open Parliament on Thursday when she sets out the government’s legislative programme.
The prime minister’s official spokesman told a Westminster briefing: “We plan to start the process [of the withdrawal agreement bill] before Christmas and will do so in the proper constitutional way in discussion with the Speaker.”
The Speaker – Lindsay Hoyle was elected to the role last month – is in charge of proceedings in the Commons.
Asked if the legislation would be identical to that introduced in the last Parliament, the spokesman said: “You will have to wait for it to be published but it will reflect the agreement that we made with the EU on our withdrawal.”
The bill is expected to pass through Parliament in time to meet Boris Johnson’s promise for the UK to leave the EU on 31 January.
Mr Johnson then has to negotiate a new trade agreement with the EU and have it ratified before the end of the post-Brexit transition period that ends on 31 December 2020. He has repeatedly said that the transition period will not be extended.
The Queen’s Speech is also expected to include legislation linked to pledges made during the election campaign – most notably a guarantee on NHS funding.
The prime minister’s spokesman also said Mr Johnson had “carefully considered” the report from the Commons Intelligence and Security Committee into alleged Russian interference in UK democracy.
“He is content publication would not prejudice the functions of those bodies that safeguard our national security,” the spokesman said.
“Publication will be a matter for the new ISC in due course.”
During the election campaign, critics said Downing Street was stalling on its release until after the election.
The report includes evidence from UK intelligence services concerning Russian attempts to influence the outcome of the 2016 EU referendum and 2017 general election.
Elsewhere, Downing Street added that the prime minister had spoken to US President Donald Trump, who congratulated him on the election result.
They discussed the “huge importance” of the UK-US relationship and looked forward to “continued close co-operation” on issues such as security and the negotiation of an “ambitious free trade agreement”.
Elsewhere, moves to get the Northern Ireland government at Stormont up and running again are also expected, with talks resuming on Monday.
New Conservative MPs have been posting pictures of themselves on their first day including the members for Bishop Auckland and Stoke-on-Trent North – Dehenna Davison and Jonathan Gullis.
