David Cameron looks to be preparing for the possibility that his plan to renegotiate Britain’s relationship with the European Union will fail. The UK prime minister would then campaign for the country to quit the EU in a referendum he plans to hold by 2017. That seems the best way to interpret his appointment of a eurosceptic foreign minister and the nomination of a little-known former lobbyist as Britain’s European commissioner.
