Ex-Foreign Secretary Boris Johnson has branded British Prime Minister Theresa May's plan for leaving the European Union "deranged," fueling tensions as the ruling Conservative Party holds its annual conference.

Johnson told the Sunday Times that May's Brexit plan won't work, particularly proposals that would require Britain and the EU to collect each other's tariffs.
"It is entirely preposterous," he said. "The idea that we could ask customs officers in Dubrovnik and Santander to charge British-only tariffs is deranged, and nobody thinks it can work. There will be economic and political damage to the U.K."
May is under siege from members of her own party as the Conservatives open their annual conference Sunday in the central England city of Birmingham.
While most conferences offer a chance for the leader to rally the troops, May's goal at this four-day gathering is to survive amid deepening opposition to her Brexit plan and growing support for a second referendum on Britain's EU membership.
May's plan would keep Britain in the EU's single market for goods while letting the country write its own rules on services and strike free-trade deals with third parties. EU leaders have rejected that idea, saying the U.K. wants to retain the benefits of EU membership without accepting its responsibilities.
Hard-line Brexit supporters also oppose the prime minister's plan because they say it would force Britain to follow rules set in Brussels, undercutting promises that the country would regain control of its own laws after Brexit.
May insisted that her plans, ratified by the Cabinet during a summer meeting at the prime minister's country estate, Chequers, remain viable, despite its rejection by EU leaders.
"Where they have problems, let's actually hear them. And it's only then that you can actually identify what the issue really is, where there are issues that lie behind this," she told the BBC's Andrew Marr program on Sunday. "My mood is to listen to what the EU have to say about their concerns and to sit down and talk them through with them."
Asked about Mr Johnson's claim that her plan was "deranged," May said: "I have just explained to you why I believe that the plan that we have put forward is a plan that is in the national interest."
