Labour is set to call on MPs to put their support behind a "jobs first" Brexit as the party looks to influence what kind of deal the UK agrees with the European Union.
In the final round of voting on the Queen's Speech - outlining the upcoming legislative programme - Labour will challenge MPs to support a Brexit which delivers the "exact same benefits" of the European single market and customs union.
It comes as party leader Jeremy Corbyn argued that Theresa May did not have a mandate for a "race-to-the-bottom" exit from the EU.
As voting concludes on Thursday, Labour hope its amendment can exploit Conservative division over Brexit priorities.
The wide-ranging amendment also reproduces many of the policies in Labour's manifesto.
Mr Corbyn has urged MPs of all sides to support it, saying that Mrs May does not have a mandate for continued austerity, as displayed by the outcome in the General Election.
But with the Prime Minister having agreed a deal with the Democratic Unionist Party to prop up the minority Tory Government, the amendment looks unlikely to pass.
Mr Corbyn said: "The Conservative programme is in tatters following the public verdict at the general election.
"Theresa May does not have a mandate for continued cuts to our schools, hospitals, police and other vital public services or for a race-to-the-bottom Brexit.
"Labour will fight these policies every step of the way.
"Labour won support in every region and nation of Britain for our jobs-first Brexit approach and our policies that would transfer wealth, power and opportunity to the many from the few.
"We invite MPs from across the House of Commons to take on board the strength of public opinion and desire for change in our country and vote for our amendment to bring forward policies to invest and improve public services, and put money in the pockets of the many not the few."
