KHARTOUM (Reuters) - Leading Sudanese opposition figure Sadiq al-Mahdi returned to Sudan on Thursday after spending two years in exile.
Mahdi, who heads one of Sudan's oldest political parties, was the country's last democratically elected prime minister.
He was overthrown in 1989 by an alliance of Islamists and military commanders that still form the nucleus of President Omar Hassan al-Bashir's all-powerful National Congress Party.
Sudan's government had accused Mahdi in 2014 of conspiring with armed rebels, a charge that could carry the death penalty, leading him to seek refuge in Cairo.
Mahdi was due to address supporters shortly.
