BERLIN, GERMANY - JUNE 29:  German Chancellor Angela Merkel speaks to the media following an extraordinary meeting with leaders of Germany's main political parties at the Chancellery the day after the European Central Bank announced it would not extend emergency funding to Greece on June 29, 2015 in Berlin, Germany. Stock markets in Europe were markedly down today and the Greek government ordered cash machines turned off and a tightening on the flow of capital in an effort to staunch citizens' withdrawals.
