Cameron: Greece must decide whether to remain in the euro
David Cameron has told the Greek people that they should decide once and for all whether to stay in the Eurozone.
The Prime Minister was speaking in America where he is attending a NATO summit with other world leaders.
He suggested that forthcoming elections in Greece would, in effect, be a referendum on the euro and said failure to provide clarity, could prove disastrous for the world economy.
