New Brexit deal agreed: Boris Johnson

London: A Brexit deal has been agreed between UK and EU negotiating teams before a meeting of European leaders in Brussels, reports said.

"We've got a great new deal that takes back control," British Prime Minister Boris Johnson tweeted on Thursday, the BBC reported.

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.

The Democratic Unionist Party (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 Prime Minister'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 Johnson have urged their respective Parliaments to back the deal.
