The Commons Brexit committee has told the UK Government it should publish its plan for leaving the EU by mid-February at the latest.
Its first report said this must set out the positions on membership of the single market and customs union.
It also called for an outline framework on the UK’s future trading relationship with the EU as part of the Article 50 negotiations and called for a commitment that the UK Parliament will have a vote on the final treaty.
A UK Government spokeswoman said it would approach the withdrawal negotiations with the “full intention of securing a deal that delivers the best possible outcome for the UK”.
She added: “We want a smooth and orderly exit from the EU, and will look at the best way to deliver that.
“We’ve also said we will set out our plans, subject to not undermining the UK negotiating position, by the end of March and that parliament will be appropriately engaged throughout the process of exit, abiding by all constitutional and legal obligations that apply.”
Scottish Brexit minister Mike Russell said he hoped Theresa May would provide more insight in her speech next week.
He added: “Brexit is the single biggest threat to Scotland’s economy so it is absolutely vital that we have clarity on our future relationship with the rest of Europe.”
