The British government says Foreign Secretary Boris Johnson has resigned, amid a widening split in the Cabinet over Brexit.

Prime Minister Theresa May's office said May accepted the resignation on Monday and will announce a replacement soon.

A leader of the campaign to take Britain out of the European Union, Johnson was under pressure to act after the resignation of David Davis as Brexit secretary.

Davis quit late Sunday saying he could not support May's plans for close trade and regulatory ties with the bloc after the U.K. leaves the European Union next year.

Davis's resignation shattered a fragile peace in May's government, which is split between supporters of "hard" and "soft" Brexit. Britain is due to leave the EU in March.

May's official spokesman, James Slack, says "we need to move forward at pace in these negotiations, and that's what we are going to do."

Top European Union officials say Brexit is becoming a mess for Europe following the resignations of the U.K.'s chief Brexit negotiator and foreign secretary.

European Council President Donald Tusk said that it is unfortunate that the whole "idea of Brexit has not left together with David Davis."

Tusk added: "The mess caused by Brexit is the biggest problem in the history of EU-UK relations and it is still very far from being resolved, with or without Mr. Davis."

Asked about his reaction to Johnson's resignation, EU Commission President Jean-Claude Juncker said sarcastically that "this clearly proves that at Chequers, there was unity in the cabinet."

Juncker's remarks were a reference to a 12-hour British Cabinet meeting at Prime Minister Theresa May's country residence on Friday that was supposed to have resolved internal disagreement over Brexit.
