Efforts by Guinea's new prime minister to relaunch a dialogue with opposition parties have been blighted by the unexplained arrest of Antoine Soromou, a leading figure in the Rally of the Guinean People (RPG) party of veteran opposition leader Alpha Conde. Mamadou Ba, the chairman of the Republican Front for Democratic Change (FRAD), a coalition of Guinea's six main opposition parties, said Soromou was arrested last Thursday. He was detained just 24 hours after opposition leaders met with recently appointed Prime Minister Cellou Dalien Diallo to relaunch a dialogue with the government.
