Tory MPs will not be told to oppose a bid to publish a leaked Brexit impact paper.
Downing Street said it would not "contest the vote" being held later on Wednesday by Labour.
The Humble Address motion would force ministers to publish the draft "EU Exit Analysis - Cross Whitehall Briefing".
It forecast Britain would be economically worse off after Brexit under every scenario modelled.
Prime Minister Theresa May's spokesman said on Wednesday: "If the House decides it wants to see the provisional analysis then we will abide by the will of the House."
Questioned why the Government previously said it would damage the UK's Brexit negotiating position by publishing impact assessments but was happy to release the new document, the spokesman responded that if MPs wanted to see it "it will be published".
