Greece to extend banking shut down - bankers

Athens - Greece's government plans to extend the closure of banks beyond Monday by at least a few more days, four banking sources said ahead of a meeting between bankers and the finance minister later on Monday.

Last week Greece issued a decree imposing capital controls and ordered banks to shut after the European Central Bank froze a vital financial lifeline following the breakdown of bailout talks between Athens and its foreign creditors.

The decree expires on Monday and the government is expected to issue a new decree to replace it.

"The bank holiday will be extended, until Friday or next Monday," one senior banker told Reuters.

Sustainable solution needed

UK prime minister David Cameron's spokesperson said on Monday that Greece and the eurozone needed to find a sustainable solution after Greeks voted 'No' to a bailout proposal.

The spokesperson 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 spokesperson 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.
