Sudan's opposition alliance on Saturday announced a 100-day plan for the peaceful overthrow of the government of President Omar al-Bashir, who has been in power for more than two decades.
"I expect the regime will fall before the 100 days finish," said Farouk Abu Issa, who represents more than 20 opposition parties.
He said the first month of the plan includes public forums and a mass rally.
Over the past year the opposition alliance has pledged to mobilise its members for peaceful protests to topple the government. It has also called for strikes by workers, but there has been no mass movement despite months of inflation exceeding 40 percent.
Scattered protests since June 2012 against Bashir's 24-year government, which calls itself Islamist, have failed to generate widespread following like the Arab Spring revolts against authoritarian rulers in North Africa and the Middle East which began in December 2010.
