MPs have backed a motion calling for an end to the public sector pay cap in the NHS, piling fresh pressure on the Government.
The Labour motion was backed by the DUP, with North Antrim MP Ian Paisley saying it sent out a "clarion call" on the issue of higher wages for doctors and nurses.
The DUP's 10 MPs are helping prop up the Tory Government following the snap election after entering into a confidence and supply arrangement.
Because the motion was not binding, their vote against it would not have amounted to a breach of their deal.
Ian Paisley said: "I've already alluded to the fact that I'm delighted that the Labour Party has brought forward this debate tonight.
"We will support them if this matter goes to a vote tonight, and it's interesting to see if we will actually get to that point."
