22 days before Britain is due to leave the EU, the two parties are yet to reach a mutually acceptable deal.
The European Union told Britain to re-work its Irish backstop proposal by Friday, but there are still fears that it will struggle to secure a deal that satisfies pro-Brexit lawmakers.
MPs will have a final say on Prime Minister Theresa May's 585-page Brexit deal with the EU, with voting scheduled for next week.
John Maytham spoke to UK correspondent Gavin Grey for more on the story.
As the clock ticks, no deal becomes more likely. Big votes happening on on Tuesday and Wednesday next week, with the minister staking her amended deal back in front of MPs saying you have got to vote for this, let's get it done.— Gavin Grey, UK correspondent - 702/Cape Talk
She went to Grimsby in the east of England where 71% of people voted to leave the EU and in her speech to workers, she said Brexit does not belong to the people of Parliament, it belongs to the people of this country. She wants to put pressure on MPs to say look, the public still wants to go, you should be enacting what the public wants.— Gavin Grey, UK correspondent - 702/Cape Talk
Grey says it is likely that very little will change in May's deal.
We are potentially leaving with no deal and it is thought that some of those who rebelled in her own party might now be feeling the pressure.— Gavin Grey, UK correspondent - 702/Cape Talk
There are people who say we need more time and indeed that could well be voted on next week Wednesday, but Theresa May said today that the EU are bound to or very likely to ask for other concessions and extra money if we go for an extension.— Gavin Grey, UK correspondent - 702/Cape Talk
