The European Central Bank will not be able to provide financial help for Greece if Athens' political negotiations with its creditors definitively break down, Bundesbank President Jens Weidmann said on Wednesday. Greece is running out of money and the ECB has been providing emergency liquidity assistance (ELA) to its banks while a political stand-off continues over an aid-for-reforms deal to prevent a looming default. In an advance copy of an interview to be published on Thursday with Italian daily La Stampa, Weidmann, who sits on the ECB's governing council, said if the talks collapse it was not the ECB's role to keep Greece afloat.
