Theresa May has written a letter to the British public pleading for their support for her Brexit deal, as the EU prepares to formally sign it off.
The UK prime minister said her agreement promises a "brighter future" for the UK and leaving the EU next year will be "a moment of renewal and reconciliation for our whole country".
EU leaders are in Brussels for a summit to decide whether to endorse the deal.
European Council chief Donald Tusk has recommended all countries approve it, reports BBC.
Spain - which had threatened to boycott the summit - will attend after a last-minute disagreement over Gibraltar was resolved on Saturday.
However, even if the EU agrees to the deal, it needs to be passed by UK Parliament, and many MPs - including in Mrs May's own Conservative Party - have stated they will vote against it.
