UK Prime Minister Theresa May said on Sunday that the Brexit withdrawal agreement, endorsed by EU leaders earlier in the day, was "the best possible" and "the only possible" deal that would ensure a "bright future" for the United Kingdom.
"This is the best possible deal. It is the only possible deal," May said at a press conference following the special meeting of the EU leaders on Brexit.
She also voiced her hope that the UK people would also qualify the deal as a "good" one.
"When they [UK people] look at this deal, they will see it as a good one for our country, and that it is in the national interest for everyone to get behind it. It honors the referendum, protects what we value, and sets us on course for a bright future. Today marks… the start of a crucial national debate in our country over the next few weeks. Before Christmas, MPs [members of parliament] will vote on this deal," May said.
The results of the vote will determine whether the United Kingdom would move toward a "brighter future" or "open the door on yet more division and uncertainty," she added.
The prime minister noted that it was clear that there should be no second referendum on Brexit.
May voiced her hope that the UK Parliament would ratify the agreement although it had faced criticism both from the opposition and from the ruling party when she defended it in the House of Commons last week.
"I will take this deal back to the House of Commons, confident we have achieved the best deal available and full of optimism about the future of our country. In parliament and beyond it, I will make the case for this deal with all my heart," May said.
She added that the House of Commons had a "duty to deliver Brexit."
May did not answer how she would manage to convince the lawmakers to support the deal.
According to the European Council, the agreement will come into force on March 30, 2019, to provide for an "orderly" withdrawal. Within the declaration, the United Kingdom and the European Union will maintain their close partnership.
