(SOUNDBITE) (English) BRITISH PRIME MINISTER, THERESA MAY, SAYING: ''It is the duty of us as politicians to deliver on the result of the vote that the British people gave in 2016 in the referendum.
They voted, we gave them the choice.
They voted to leave the EU.'' It was an embarrassing start to five days of parliamentary debate over Brexit for Theresa May.
First her government was found to be in contempt of parliament for failing to publish its full legal advice on Brexit.
Then a group of her own Conservative MPs won a challenge to hand more power to the House of Commons if her unpopular deal is voted down.
(SOUNDBITE) (English) CONSERVATIVE LAWMAKER, BOB SEELEY, SAYING: "It is unfortunate for the government to be in contempt of parliament.
Would she agree that it is worse for parliament to be in contempt of the British people, which is what will happen if we do not deliver on Brexit." Opposition - from within her own party and beyond - remains fierce, just a few days ahead of the "meaningful vote" on December 11.
May hopes to secure parliament's approval for her Brexit deal that was rubber-stamped by EU leaders in Brussels.
If she wins that vote, Britain will leave the EU on March 29 - marking its greatest trade and foreign policy shift in over 40 years.
But the odds are stacking up.
May has warned lawmakers that if they fail to back her - Britain could crash out of the EU, risking economic chaos.
(SOUNDBITE) (English) BRITISH PRIME MINISTER, THERESA MAY, SAYING: It is not easy when the passions run so deep, but looking around this chamber I know that we can meet this moment.
So I promise you today: this is the very best deal for the British people.
I ask you to back it in the best interests of our constituents and our country and with my whole heart I commend this motion to the House." May has four more days of debate to convince the skeptics ahead of the all-important vote.
