The guiding body of Jordan's largest opposition group has resigned en mass, accepting responsibility for the movement's poor showing in recent parliamentary elections, the group's spokesman said Friday. The Muslim Brotherhood also levied criticism against the government, claiming the Nov. 20 elections for the lower house of parliament were rigged. "The fraud and government interference in the electoral process resulted in the winning of other candidates at the expense of the Islamists," the movement's spokesman, Jamil Abu Bakr, told The Associated Press. The government has repeatedly denied the allegations. "The Shura Council, which made the decision to participate in the elections, felt responsible and decided to dissolve itself," Abu Bakr added.
