LONDON—Three lawmakers from Britain’s governing Conservatives quit over the government’s “disastrous handling of Brexit” on Feb. 20, in a blow to Prime Minister Theresa May’s attempts to unite her party around plans to leave the European Union.
The lawmakers, who support a second European Union referendum and have long said May’s Brexit strategy is being led by Conservative eurosceptics, said they would join a new independent group in parliament set up by seven former opposition Labour politicians.
