MOHAMED Ibrahim Nugud, head of Sudan’s Communist Party, died on Thursday after more than four decades at the helm of what was once one of the African country’s most potent political forces, the party said.Nugud, born in 1930, became the party’s secretary general shortly after President Jaafar Nimeiri had his predecessor executed in a broad purge of the party’s leadership following a failed coup in 1971.Known for his personal charisma, Nugud led the party through the intervening years, which saw resumption of civil war with the country’s south, Nimeiri’s ousting in a popular uprising and a coup which brought the current military government to power.
