Junior Brexit Minister David Jones told the House of Commons the vote will cover both leaving the EU and Britain’s future relationship with the bloc.
He said: “We intend that the vote will cover not only the withdrawal but also the future relationship with the EU.
“I can confirm the Government will bring forward a motion on the final agreement to both Houses before it is concluded and we intend for this to happen before the European Parliament debates and votes on the final agreement."
The move can be seen as an attempt by ministers to offer a concession to would-be rebel Conservatives by offering MPs a vote on the final Brexit deal "before it is concluded".

As the House reacted to the Government's concession, Mr Jones said: “The Government has repeatedly from this dispatch box committed to a vote on the final deal, a vote in both Houses before that deal comes into force.
"This I repeat and confirm will cover not only the withdrawal agreement but future arrangement we propose with the EU.
“I can confirm again that the Government will bring forward a motion on the final agreement to be approve by both Houses before it is concluded and we expect and intend that this will happen before the European Parliament votes debates and votes on the final agreement.”

It comes as Jeremy Corbyn orders Labour MPs to back the Bill in its final House of Commons stage on Wednesday, paving the way for Theresa May to trigger the formal exit process.
A Labour source said Mr Corbyn is is imposing a three-line whip on his MPs in a move which risks the resignation of high-profile shadow cabinet ministers like Clive Lewis.

Shadow Brexit secretary Keir Starmer clashed with SNP MP Pete Wishart over the amendments.
Mr Wishart, MP for Perth and North Perthshire. “Is it the case that if all amendments are rejected by the Government, the Labour Party are simply going to endorse the third reading vote and support the government.
"What is the point therefore of making all this case for these amendments if you supinely just cave into what Government want on Article 50.”
Mr Starmer said: “I’m not sure how helpful interventions like that are to a debate which is actually really important about the scrutiny and accountability.
“Just to be clear nagging away, pushing votes and making the argument over three months we have got a White Paper and it is important. We have got reports about reporting back.

The first day of committee stage ended on Monday following three votes on amendments, which the Government defeated.
