Britain says Greece and euro zone need a sustainable solution

LONDON (Reuters) - Greece and the euro zone need to find a sustainable solution after Greeks voted 'No' to a bailout proposal, British Prime Minister David Cameron's spokeswoman said on Monday. The spokeswoman said it was in Britain's interests for Greece to find a solution. When asked whether Greece should stay in the European Union, Cameron's spokeswoman said Britain supports a 28-member EU. "Clearly Greece and the euro zone need to sit down and talk through the implications of the result and what happens next. They need to find a sustainable solution," she added.
