ATHENS: Greece will put off by a month the sale of majority stake in its biggest ports, Piraeus and Thessaloniki, the head of the country’s privatisation agency said in a newspaper interview published on Saturday. Setting a date to submit binding bids for Piraeus and Thessaloniki ports is one of the actions that Athens needs to complete to conclude its first bailout review and unlock more funds for its 86 billion euro (63 billion pound) bailout. “The submission (of bids) for OLP (Piraeus Port operator) will take place on November 30 or early December at the latest,” the Head of privatisation agency (HRADF) Stergios Pitsiorlas told the Kathimerini newspaper. China’s Cosco Group, Danish container terminal operator APM Terminals and Philippines-based International Container Terminal Services have until October 30 to submit binding bids for a 51 per cent stake in OLP.
