On Sunday, European leaders approved Britain’s departure from the 28-member EU bloc after more than 40 years of membership.
The two documents approved at the summit in Brussels were the legally binding 585-page withdrawal agreement and a political declaration. Between them, they set out the terms of the UK leaving the bloc and the future relationship between both sides.
The UK is scheduled to leave the EU on 29 March 2019.
The next step is for May to try and get MPs to back the deal, with most currently standing against it. MPs are set to vote on the divorce deal with the European Union before Christmas.
The main sticking point ahead of Sunday’s summit had been the issue of Gibraltar. However, a last-minute fix was found.
Yet Northern Ireland DUP leader Arlene Foster said Saturday she would vote against the deal if the Irish backstop is not removed from the agreement, fearing a separate customs arrangement between Northern Ireland and mainland Britain could lead to the breakup of the UK.
