ATHENS – A Greek court sentenced the leadership of the extreme-right Golden Dawn party to 13 years in prison Wednesday, imposing the near-maximum penalty for running a criminal organization blamed for numerous violent hate crimes.Presiding judge Maria Lepenioti read out the sentences against party leader Nikos Michaloliakos and seven other former lawmakers.The landmark ruling follows a five-year trial of dozens of top officials, members and supporters of Golden Dawn, an organization founded as a neo-Nazi group in the 1980s that rose to become Greece’s third-largest political during a major financial crisis in the previous decade.Eleven other former parliament members were jailed for between five and seven years for membership of a criminal.
