ATHENS, Greece (AP) — The heads of the three parties in Greece’s new coalition government are to meet again Wednesday to try and agree on further austerity cuts strenuously demanded by the country’s bailout creditors.

Despite two meetings in less than a week, conservative Prime Minister Antonis Samaras and junior coalition party chiefs have not finalized new politically costly measures intended to save €11.5 billion ($14.13 billion) in 2013 and 2014.
