DUP leader Arlene Foster has threatened to drop the deal keeping Theresa May’s Government in power if her Brexit deal is passed.
Foster, 48, told BBC Radio Ulster’s Inside Politics: “If she is successful in Parliament, and there is no evidence that she is going to be successful in Parliament, then of course we will have to revisit the confidence and supply agreement.
“That agreement was about giving national stability, it was acting in the national interest and delivering on Brexit.
“If this is not going to deliver on Brexit then of course that brings us back to the situation of looking at the confidence and supply agreement, but we are not there yet and we are not going to jump ahead until we see what happens in Parliament.”
The Democratic Unionist Party effectively became kingmakers after the 2017 general election thanks to the confidence and supply deal that was struck with the Conservative party to keep May in power.
It means the DUP’s ten MPs will vote with the Tories on key measures such as the Budget and any votes of no confidence that could topple the government.
Founded by Protestant firebrand Ian Paisley, the DUP was once a fringe party but is now the largest in Northern Ireland, with a narrow electoral edge over republicans Sinn Fein.
May has already found herself in hot water over the DUP when they recently went on strike during voting on the recent Finance Bill earlier this week.
Their refusal to back the Government on the all-important money legislation is a clear breach of the ‘confidence and supply’ agreement that cost taxpayers £2billion.
But senior DUP sources last night told The Sun the party would continue to stay away from Commons votes until Mrs May agrees to rip up her controversial Irish backstop.

A senior DUP figure told The Sun at the time: “I don’t think we’ll see much Government legislation tabled next week, as they know what we’ll do now.
“They are breaking the agreement, not us. They are nor delivering on our joint priorities – which is the Union.”
Yesterday, the under fire Prime Minister refused three times to rule out resigning if the Commons voted down her Brexit deal, while issuing a new threat to any rebel Tory MPs.
Challenged in a phone-in, she ducked the question and would only say she was “focused” on delivering the result of the 2016 Referendum.
