Prime Minister Theresa May will ask MPs to give her more time to secure changes to the controversial part of her Brexit deal - the Northern Irish backstop.
Mrs May is due to report back to MPs this week, after trying to persuade the EU to make last-minute changes.
According to the BBC's Iain Watson, the PM will promise Parliament another vote on other Brexit options if a deal is still not ready by the end of February.
Labour wants to hold Mrs May to her word and make sure the vote is held.
The shadow Brexit secretary, Sir Keir Starmer, has said Labour has drafted an amendment which, if passed this week, would guarantee a vote by the end of the month.
He accused the prime minister of "running down the clock" so that Parliament will only have a choice between her Brexit deal, and a no-deal exit.
