SOME 4,2 million voters head to the polls on Sunday to restore democracy to Niger in a presidential vote brought about by the assassination of the previous incumbent. The elections were promised by Niger’s military junta on the heels of their putsch in April, when presidential guards gunned down president Ibrahim Bare Mainassara as he was about to board a plane at a Niamey airport. The junta’s commander Daouda Mallam Wanke has called Sunday’s vote the “last chance” Niger has to rehabilate itself after 10 years of political chaos and economic turmoil. 50 teams of international observers will scrutinise the process throughout the country.
