Ministers have agreed to publish the government's full legal advice
on the deal after MPs found them in contempt of Parliament for issuing a
summary.
And MPs backed calls for the Commons to have a direct say in what happens if her deal is rejected next Tuesday.
Mrs May said MPs had a duty to deliver on the 2016 Brexit vote and the deal on offer was an "honourable compromise".
Mrs May was addressing the Commons at the start of a five-day debate on her proposed agreement on the terms of the UK's withdrawal and future relations with the EU.
The agreement has been endorsed by EU leaders but must also be backed by the UK Parliament if it is to come into force. MPs will decide whether to reject or accept it on Tuesday 11 December.
