BRUSSELS (AP) -- The head of the European Parliament is calling on British Prime Minister David Cameron to quickly clarify what proposals he has for the fundamental reform of the European Union to ensure Britain's continued membership of the bloc.
EU Parliament President Martin Schulz said Thursday ahead of a summit of EU leaders that "above all, we need clarity on what we will be discussing over the next few months."
Cameron is to have lunch with Jean-Claude Juncker, the head of the executive Commission, before discussing Britain's plans further on the sidelines of the summit.
EU nations are increasingly frustrated that Cameron hasn't made concrete proposals yet. Cameron plans to hold a national vote before the end of 2017 on whether Britain should leave the EU -- a possibility known as Brexit.
