New Democracy has condemned a violent protest against former conservative minister Makis Voridis ahead of a press briefing in Kavala, northeastern Greece.

On Friday, employees at Kavala Oil stormed the hotel where the event was to take place and caused extensive damage to the premises, while Voridis remained in his room.

Workers were protesting a new contract for exploitation of fuel deposits in the Prinos oil field in the Aegean Sea which awards joint rights to the mother company Energean Oil & Gas.

“The workers came here asking for trouble. We wanted to talk with them, but they didn’t give us a chance,” the local party organization said in a statement.
