A Brexit deal has been agreed between UK and EU negotiating teams before a meeting of European leaders in Brussels.
Prime Minister Boris Johnson tweeted: "We've got a great new deal that takes back control."
The two sides have been working on the legal text of a deal, but it will still need the approval of both the UK and European parliaments, BBC reports.
The DUP has cast doubt on its sign off, saying they still cannot support it.
The Northern Irish party earlier released a statement saying they could not back proposals "as things stand", and - after the PM's announcement - said their statement "still stands".
But European Commission President Jean-Claude Juncker said it was a "fair and balanced agreement".
Both he and Mr Johnson have urged their respective parliaments to back the deal.
