Africa: Tough questions for former heads of state

A public discussion with eleven former African leaders attending an African Presidential Roundtable, crowned the two-day event held at the University of the Witwatersrand (Wits) in Johannesburg recently. About four hundred people -- including staff, students, invited guests and other members of the public -- filled the Wits Great Hall for an exchange of views with the ex-leaders. British Broadcasting Corporation (BBC) Africa bureau chief Milton Nkosi moderated the proceedings, which saw the floor opened for queries to the former presidents.
