London - Prime Minister Theresa May faces strong opposition on Tuesday as she tries to persuade lawmakers to back her plans for Britain to withdraw from the European Union.
Lawmakers will vote on several non-binding amendments to May's plans, which she submitted following a crushing defeat on the deal she has negotiated for Britain to leave the EU on March 29.
One key amendment seeks to commit the government to renegotiating a "backstop" arrangement designed to guarantee an open Irish border after Brexit, while another proposes extending the Brexit negotiating process beyond March.
The Commons, parliament's main elected house, rejected the withdrawal deal by 432 votes to 202 on January 15, delivering the biggest-ever defeat to a British government.
Lawmakers are expected to press May during Tuesday's debate to indicate when a second vote might be held on the deal.
