A defiant British government has doubled down, insisting it will leave the European Union in 11 days despite parliament's forcing a reluctant prime minister to request another delay.
On a day of high drama on Saturday, MPs in the House of Commons passed up the chance to decide on the revised withdrawal agreement that Prime Minister Boris Johnson had negotiated with the European Union.
That defeat leaves Johnson under mounting pressure to find a way out of paralysing impasse on when and how Britain would leave the EU after the country narrowly voted to exit in a 2016 referendum.
Johnson has reluctantly sent European Council President Donald Tusk a letter legally imposed on him by parliament requesting an extension -- but refused to sign it.
The Conservative leader sent a second, signed letter insisting he was not seeking an extension to the Brexit deadline, which has already been postponed twice, warning that "a further extension would damage the interests of the UK and our EU partners".
Having failed to back a divorce deal, which Johnson had secured on Thursday, MPs triggered a law requiring him to write to EU leaders asking to delay Brexit to avoid the risk that Britain crashes out in less than a fortnight.
Senior cabinet minister Michael Gove, the government's Brexit planning chief, was nonetheless adamant that Britain would leave the EU on schedule.
"Yes. We are going to leave on October 31. We have the means and the ability to do so," he told Sky News.
Although Sterling fell on Monday, losses were limited by hopes the country can eventually avoid crashing out of the EU without a divorce agreement in place.
"We can say it (the pound) is holding firm, which shows hopes (for avoiding no-deal Brexit) have not been dashed," Shinichiro Kadota, exchange strategist at Barclays Securities in Japan, told AFP.
EU 'fed up': Raab
The government will bring forward this week the domestic legislation needed to implement the divorce deal, with a first vote as soon as Tuesday.
Separately, it is seeking a new yes-or-no vote on approving the deal on Monday, although this may fall foul of parliamentary procedure.
Commons Speaker John Bercow will rule on whether Johnson can hold a "meaningful vote" on the deal.
"If we get the legislation through then there is no extension. October 31 is within sight," said Gove.
He said it was dangerous to assume that the 27 other EU leaders would grant an extension.
More than three years on from the June 2016 vote to leave the EU, Foreign Secretary Dominic Raab told the BBC that from his conversations with other EU capitals, "they are fed up with this now -- and we are fed up with it".
The Labour main opposition has lambasted Johnson's deal as a "sellout" and voted for the delay.
However, senior figures hinted Sunday that they could let it go through, subject to amendments including a second referendum pitting a divorce deal against remaining in the bloc after all.
"What we are trying to achieve is that this deal in particular, but any deal, is put up against Remain in a referendum," the party's Brexit spokesman Keir Starmer told the BBC.
"And we will have to see tactically how we get there."
Europe mulls response
Brussels officials pressed on with plans to ratify the divorce deal as European leaders considered Johnson's delay request.
Ambassadors and senior officials from the other 27 member states met Sunday.
"The EU is keeping all options open and has therefore initiated the ratification process so that it can be handed over to the European Parliament on Monday," an EU diplomat told AFP.
"The EU will probably pursue this strategy until there is clarity on the British side," he said, speaking on condition of anonymity.
Tusk will spend a "few days" canvassing member state leaders, and diplomats said this would mean the British parliament will have to vote on Brexit again before hearing their decision on the October 31 departure.
MPs voted by 322 votes to 306 on Saturday to support former Conservative MP Oliver Letwin's amendment to buy extra time.
Letwin said he would now switch and vote for the deal. Former interior minister Amber Rudd said the same, meaning Johnson is just a few votes short.
"We appear to have now the numbers to get this through," said Raab.
The Brexit date has already been pushed back twice from March 29, to the fury of those who wanted to abandon Britain's European project after nearly 50 years.
