Plevris cleared Controversial lawyer and author Costas Plevris yesterday had a 14-month suspended jail sentence overturned after an Athens appeals court ruled that he was not guilty of inciting racial hatred. Plevris had been handed the sentence after his book «Jews: The Whole Truth,» which denies the Holocaust took place, was deemed an insult to the Jewish community. Plevris was cleared of the offenses by four votes to one. The Central Jewish Council of Greece said it was «saddened and concerned.» Jailed sailors The Foreign Ministry lodged a complaint yesterday with the Venezuelan Embassy in Athens over the fact that two Greek seamen jailed in Maracaibo last October after local coast guard officers found 100 kilos of cocaine hidden on the Astro Saturn bulk carrier, have not yet been charged.
