KHARTOUM, April 1 (Xinhua) -- The opposition may nominate one candidate for the presidential race, said a major Sudanese opposition leader Thursday, only a few hours before a meeting for Sudanese opposition parties to decide their position towards the elections.

"The opposition parties may agree to support one presidential candidate to compete with candidate of the National Congress Party (NCP), Omar al-Bashir," Mubarak al-Fadil al-Mahdi, chairman of National Umma Party (Reform and Renewal), told reporters in Khartoum Thursday.

He suggested that the opposition parties could agree also to partial elections and exclusion of the Darfur region until the Darfur crisis is resolved.

"It will be difficult to conduct the elections in Darfur under the deteriorated security conditions there," he said.

Sudanese opposition political parties recently submitted a memo to the Presidency and the National Elections Commission (NEC), demanding postponement of the elections until November, but the Sudanese president refused to postpone the elections even for "a single day".

This year's general elections will be the first multi-party elections in Sudan in more than 20 years.
