Lawmakers in British Prime Minister Theresa May's Conservative Party on Tuesday proposed a last-minute compromise Brexit plan which seeks to draw a line under internal divisions that have so far prevented Parliament from approving an exit deal.

May is under acute pressure to find a way out of Britain's worst political crisis since World War II after her proposed deal for leaving the European Union was overwhelmingly rejected by Parliament earlier this month.

The new plan aims to broker peace between Conservatives who voted "leave" and those who voted "remain" in the 2016 Brexit referendum and has been endorsed by senior figures from both sides. The small Northern Irish party that props up May's minority government has also indicated its support.
