MUNICH (Reuters) - European Central Bank policymaker Jens Weidmann on Wednesday urged Greek banks receiving so-called emergency liquidity assistance (ELA) from their national central bank to improve their liquidity position.

Earlier on Wednesday, a banking source told Reuters the ECB had raised the cap on ELA that Greek banks can draw from the country's central bank to above 71 billion euros ($77.84 billion) from 69.8 billion previously.
