May embroiled in chaos over Brexit

LONDON — Prime Minister Theresa May defied mounting calls to quit or change course Thursday over Britain’s withdrawal from the European Union, warning that abandoning her Brexit plan would plunge the country into “deep and grave uncertainty.”

Britain’s long-simmering divisions over its future in the EU erupted into turmoil just a day after the government agreed to a divorce deal with the bloc. Two Cabinet ministers resigned, and some lawmakers from May’s own party called for her to be replaced. The crisis threatened to destroy the Brexit agreement, unseat the prime minister and send the U.K. hurtling toward the EU exit without a plan.

In an evening news conference aimed at regaining some control, May said she believes “with every fiber of my being that the course I have set out is the right one for our country and all our people.”

“Am I going to see this through? Yes,” she said.

The hard-won agreement with the EU has infuriated pro-Brexit members of May’s divided Conservative Party. They say the agreement, which calls for close trade ties between the U.K. and the bloc, would leave Britain a vassal state, bound to EU rules it has no say in making.

May insisted that Brexit meant making “the right choices, not the easy ones” and urged lawmakers to support the deal “in the national interest.”

But she was weakened by the resignation of two senior Cabinet ministers, including Brexit Secretary Dominic Raab. Hours after he sat in the meeting that approved the deal, Raab said he “cannot in good conscience” support it.

Work and Pensions Secretary Esther McVey followed Raab out the door. She said in a letter that it is “no good trying to pretend to (voters) that this deal honors the result of the referendum when it is obvious to everyone that it doesn’t.”

A handful of junior government ministers also quit, and leading pro-Brexit lawmaker Jacob Rees-Mogg called for a vote of no-confidence on May.

Rees-Mogg said May’s deal “is not Brexit” because it would keep Britain in a customs union with the EU, potentially for an indefinite period. He said May was “losing the confidence of Conservative members of Parliament.”

Rees-Mogg called for May to be replaced by a more firmly pro-Brexit politician, naming ex-Foreign Secretary Boris Johnson, former Brexit Secretary David Davis and Raab as potential successors.

Thursday’s political mayhem prompted a big fall in the value of the pound.
