May suffers defeat on key Brexit legislation

Unelected upper chamber votes to remain in EU's single market

LONDON - Britain's upper house of parliament on Tuesday inflicted another embarrassing defeat on Prime Minister Theresa May's government on Tuesday, challenging her plan to leave the European Union's single market after Brexit.

May, who has struggled to unite the government behind her vision of Brexit, has said that Britain will also leave the European Union's single market and customs union after it quits the bloc next March.
