British Prime Minister Theresa May is warning Members of Parliament to back her Brexit deal or risk undermining people's faith in democracy.
Writing in the Sunday Express, two days ahead of a crucial parliamentary vote on how Britain will leave the EU, May said it is time to forget the games and do what is right for the country.
Rejecting her proposed package, she said it "would be a catastrophic and unforgivable breach of trust in our democracy. So my message to Parliament this weekend is simple: it is time to forget the games and do what is right for our country".
May's plea comes as a cross-party group of MPs is thought to be planning to take control of the Brexit process if, as is widely expected, her deal is rejected during a Commons vote on Tuesday.
Opposition Labour leader Jeremy Corbyn told the BBC his party would table a vote of no confidence against the Prime Minister if she loses.
"My own view is I'd rather get a negotiated deal now if we can to stop the danger of a no deal exit from the EU on the 29th March, which would be catastrophic for industry, catastrophic for trade and the long-term effects of that would be huge," Corbyn told the BBC's Andrew Marr Show on Sunday.
"I think parliament did vote for an amendment to the finance bill this week which indicated its opposition to no deal but there isn't totally specific on it, we will do everything we can to prevent a no deal exit," he added.
On Saturday, rival protesters clashed in London during separate pro-Brexit and anti-austerity demonstrations. Both groups wore high-visibility jackets, in reference to the French Yellow Vest movement, now in its tenth week of anti-government protests.
Meanwhile, UK police arrested pro-Brexit activist James Goddard on public order offenses in connection with incidents outside the UK Parliament on Monday, during which Remain-supporting Conservative MP Anna Soubry was called a Nazi.
Goddard has not been charged and has been released on bail until next month.
