Euro zone shares sink after Greeks vote \\\'No\\\'

The euro zone's blue-chip share index fell 1.7 per cent on Monday after Greek voters rejected austerity measures demanded in return for a debt deal, raising concerns about the country's possible exit from the euro zone. Banks were the worst hit, with the Euro STOXX banks index down 2.1 per cent. Italy's Unicredit and Intesa Sanpaolo both were down more than 3 per cent. Spain's Santander, France's Societe Generale and Germany's Deutsche Bank all fell about 2.5 per cent. The euro zone's blue-chip Euro STOXX 50 index was down 1.7 per cent by 0803 GMT, while the pan-European FTSEurofirst 300 index fell 1.2 per cent, according to Reuters.
