ATHENS: Greek gaming giant OPAP has sued the state for over a billion euros in damages over a new tax and a dispute over a video lottery contract. “The company filed today a request for arbitration under the 2011 VLT Licence Agreement with the London Court of International Arbitration for damages in excess of one billion euros,” OPAP said late Thursday. OPAP said it had been forced to suspend the installation of thousands of video lottery terminals owing to restrictions imposed by the Greek gaming commission. OPAP was also angered by a new tax law drafted by the leftist government and approved in parliament last week.
