Boris Johnson needs to sell his last-minute Brexit deal to MPs before a crunch vote, as he returns from Brussels in a "very confident" mood.
The Prime Minister said there is a "very good case" for MPs to vote in his favour in what is expected to be a dramatic and historic House of Commons showdown on Saturday.
Mr Johnson has urged parliamentarians to "come together and get this thing done" after EU leaders approved the deal before the key summit began in Brussels on Thursday
He appealed to those in Northern Ireland as well as across party lines in order to encourage support for the deal.
"I am very confident that when my colleagues in Parliament study this agreement that they will want to vote for it on Saturday and in succeeding days," he said.
