5th installment agreed

European Ministers agreed the 5th installment of loans to Greece. The Greek press has welcomed this move but the main opposition party ND (Conservative) made it clear that they will not be voting with the government when it comes to budget setting later on in the year. That vote would require 180 MPs to be in favor and the PASOK government can only rely on 155. Does this mean that there will be an election soon and if yes how would the 'agreement' with Europe work? Its a mess!
