Hungary's ruling right-wing Fidesz party quit the conservative European People's Party (EPP) grouping in the European Parliament Wednesday, Prime Minister Viktor Orban said. "I hereby inform you that Fidesz MEPs resign their membership in the EPP group," Orban said in a letter to EPP group leader Manfred Weber posted on Twitter by one of Orban's ministers. The decision to quit followed a vote by the group to adopt a rules change that was billed as a way to expel Orban's party from their ranks. pmu/lc
