DUP leader Arlene Foster has insisted there are no splits in her party over Brexit.
Mrs Foster spoke out amid reports that seven out of her 10 MPs backed the British government’s withdrawal deal.
"No, there's no splits within the Democratic Unionist Party," she said.
"I'm not quite sure where that's coming from."
Her comments came as MPs gathered last night to vote on four alternative withdrawal proposals.
These included proposals for a “Norway Plus” arrangement, a plan from Europhile Tory grandee Kenneth Clarke for a customs union with the EU after Brexit and a demand from Labour backbenchers Peter Kyle and Phil Wilson for a referendum on any Brexit deal passed by parliament.
SNP MP Joanna Cherry's also called for powers for MPs to vote to block a no-deal departure.
Proposals for the "Norway-plus" plan, which would mean close UK engagement with the EU after Brexit, received support from both Labour and the Scottish National Party last night.
Meanwhile, Irish foreign affairs minister Simon Coveney has said there is still time to create a plan that would protect the single market and peace process in the absence of a backstop.
Asked whether it was too late with the April 12 date looming, he said: "No, it's not, because we need to continue to focus on the solution here, which is a solution that was agreed by the British Government and the EU institutions, which was to solve this problem on the basis of regulatory alignment.
"If the British Government refuse to follow through on that commitment that they have made well then, of course, we've to speak to the EU Commission about how we respond to that and that was always going to be left to the last number of weeks."
