Earlier in the day, The Independent reported that senior Conservative ministers had admitted that even if May wins the Tuesday vote, there would still not be enough time to prepare the amount of legislation needed to leave the bloc by 29 March.
It's after he was overheard in a conversation with the Transport Minister saying there will have to be checks on goods in the event of a no deal Brexit. "There were 20,000 soldiers in Northern Ireland and they couldn't hermetically seal the border in Northern Ireland".
Moments after the defeat Labour Party leader Jeremy Corbyn announced that he had tabled a vote of no confidence in the Government.
Mr Davis said the changes meant his former department had become "unpredictably handicapped".
He said: "I would anticipate that there would be checks".
"We have no such secret plan".
Asked on the BBC's Good Morning Ulster programme on Tuesday whether Theresa May was the best person to lead the United Kingdom out of this pickle, DUP deputy leader Nigel Dodds simply said: "Well, she leads the best party to do it, because they have more seats than anyone else".
When Foster said "we never had a hard border" in Ireland, however, people responded in disbelief.
British PM May cautions of 'catastrophe' if Brexit plan rejected
Mr Corbyn has said his party wants to have a general election, a possibility Mr Blackford said the SNP would be prepared for. But if MPs vote to reject the withdrawal agreement, Britain will, as the prime minister has said, be in uncharted waters.
We know the Democratic Unionist Party (DUP) will support prime minister Theresa May's government in Wednesday's no-confidence motion, because it has said it will.
Speaking to the media, she said: "I've asked the Tanaiste a couple of times, directly, face to face, "have you done any contingency planning for a border on this island" and I have been told unequivocally absolutely not".
Sinn Fein leader Mary Lou McDonald told the Dail (Irish parliament) there was an "unmissable hostility" to Irish interests in some sections of British political establishment.
On 15 January, the DUP's Arlene Foster explained her party's opposition to the Brexit backstop deal for Northern Ireland.
"It's like the scene in Fawlty Towers: 'Whatever you do don't mention the war, '" added Martin, whose party is supporting Varadkar's Fine Gael in a confidence and supply deal similar to Theresa May's deal with the DUP.
Mr Varadkar said he "remembers very well" the hard border that existed during the Troubles.
"The reality is in the absence of backstop, there will be a hard border and there will be checks".
He said: "If a deal is impossible, and no one wants no deal, then who will finally have the courage to say what the only positive solution is?"
