Public Order Minister Vyron Polydoras called on police on Monday to drop plans for a May 23 strike, the day the soccer Champions League final will be held in Athens, in order to avoid compromising security at the event. Police unions have said they are considering a strike to support demands for improved wages and working conditions following a series of attacks on police targets by self-styled anarchists in recent weeks. The minister requested the strike date be changed and said that he was acting as an adviser to police rather than in his capacity as the public order minister, a ministry source said. Police union representatives did not reply on Monday and said they will make their final decision between May 15 and 23. More than 17,000 officers are expected to be on duty in the capital for the final.
