The Government is understood to have lined up December 30 and possibly December 31 to vote on any deal agreed between the UK and Brussels. Parliament broke up for Christmas last Thursday but were warned they could be recalled at any point to vote on a deal.
MPs must be given at least 48 hours notice before being asked to return to Westminster.
No10 has ruled out asking MPs to sit on Christmas Day and Express.co.uk understands they will not be asked to sit over the bank holiday weekend.
However, the Commons could return next Wednesday, just 48 hours before the end of the transition period.
A Government source said MPs would not be asked to return to the Commons before that date as “a gesture of goodwill”, even if a deal is agreed imminently.

The source told The Telegraph: “Is it good form this side of Christmas, doing it so late?
“MPs would like to read the thing first.
“After Christmas would give it a bit of breathing space and give drafters a bit more time to make sure everything is watertight.”
Before any trade deal agreed between the UK and EU can come into force it must be given approval by Parliament.

“I’m sure the whole House will agree the country would expect nothing less.”
However, Tory backbenchers are bracing themselves to have to return to the Commons to vote on legislation regardless of whether a trade deal is brokered.
One told Express.co.uk they were preparing to have to vote on no deal contingency measures before January 1 if negotiations failed to find a breakthrough.
They said: “I would think it’s likely we’re going to be sitting one way or the other. The question is, what are we going to be debating? Are we going to be debating a deal or are we going to be debating no deal?
“If there’s an announcement we’re going for no deal, Parliament will need to be reconvened for a debate on it.
“That would be normal.”
The MP added: “There will need to be contingency plans.
“If we are going with no deal it may be we need emergency legislation.”
