LONDON (AP) — Britain's Prime Minister Theresa May has pleaded with lawmakers to accept her deal for leaving the European Union, warning that faith in democracy was at stake.

Writing in the Sunday Express ahead of a critical vote this week, May urged lawmakers to "do what is right for the country," because she said rejecting the will of the people would be "a catastrophic and unforgivable breach of trust in our democracy."

May has urged Parliament to support her little-loved EU divorce deal so that Britain doesn't leave the EU on March 29 without an agreement on exit terms.

She postponed a vote in mid-December when it became clear lawmakers would resoundingly reject the Brexit deal, but a compromise measure has left both pro-European and pro-Brexit politicians unhappy.
