BELFAST — U.K. Prime Minister Theresa May should not waste time with a parliamentary vote and instead seek a new Brexit deal with Brussels, Arlene Foster said today.

The leader of the Democratic Unionist Party, whose 10 MPs prop up the U.K. prime minister's government, insisted the draft Withdrawal Agreement, which was agreed in principle on Thursday, could be reopened.

"As it currently stands, [the Withdrawal Agreement] is not going to get the support in parliament, I think that is very very clear, so instead of wasting time promoting a deal that is not actually going to get support, wouldn't it be much better to use that time to get a better deal?" she asked.

Foster cited Spain's push to reopen the deal over the future status of Gibraltar as an opportunity for the prime minister to seek a better deal.

Speaking to the BBC's "Inside Politics" program in Northern Ireland, Foster also accused Brussels negotiators who dismissed technological border solutions last year of wasting time. She said an agreement should be reached that no hard border would be put up on the island of Ireland.

"Who is going to put this hard border in place? It has now taken on an almost mythical status if you like and wouldn't it be better to spend our time getting a deal not just for Northern Ireland but for the whole of the U.K," she added.

The DUP would be “looking again” at its confidence and supply deal with the Conservatives if they don’t deliver on Brexit, Foster said.

She told the BBC the party had entered the agreement to create national stability and to deliver Brexit.

"If this is not going to deliver on Brexit then of course that brings us to the situation of looking again at the confidence and supply deal."

"But we are not there yet," she said.
