Bundesbank President Jens Weidmann has spoken out against increasing the liquidity assistance provided by the Eurosystem to Greece. If short-term assistance was thought to be necessary, it was up to politicians to provide it, he said at a Bundesbank conference in Frankfurt am Main. Greece needed to keep capital controls in place until an appropriate support package had been agreed by all parties and the solvency of both the Greek government and the Greek banking system had been ensured, said Mr Weidmann.
