David Cameron has offered a referendum on whether to leave the European Union if his party wins the next election. Despite his plans to renegotiate Britain’s relationship with the EU, which are viewed with skepticism in Berlin, Merkel spokesman Steffen Seibert praised the two leaders’ strong relationship, “which matches the close friendship and partnership with Great Britain.” Cameron, accompanied by his wife and children, is expected to discuss “all aspects” of European reform, along with the upcoming Group of Eight summit in Ireland and the conflict in Syria, according to Downing Street. The Camerons will stay Friday and Saturday at government guest house Merseberg near Berlin.
