Greek Prime Minister Lucas Papademos has failed to secure the support of his coalition for a raft of new austerity measures designed to secure a deal leading to a fresh bailout package.

He met officials from three parties and had over seven hours worth of talks on Wednesday.

The main stumbling block appears to have been proposed pension cuts.

"There was broad agreement on all the program issues with the exception of one, which requires further elaboration and discussion with the troika. This discussion will take place immediately, so as to conclude the agreement in view of the Eurogroup meeting," a statement issued by the prime minister's office said.

Mr Papademos, a technocrat who leads a cabinet of party politicians, said after the talks broke up in the early hours that he wanted agreement to be reached before eurozone finance ministers meet in Brussels on Thursday.
