Nicaraguans went to the polls on Sunday with former revolutionary leader, Daniel Ortega, hoping to win a fourth consecutive term. He didn't leave much to chance. Prominent opposition figures (including presidential candidates) and critics were imprisoned or forced into exile and newspaper offices raided. It seems likely that his Sandinista National Liberation Front (FSLN) will receive a significant portion of the popular vote and Ortega – and his wife and vice-president Rosario Murillo – will continue to rule Nicaragua for the foreseeable future. Eline van Ommen traces the story of the young 1970s left-wing revolutionary, and how the duo have managed to cling on to power.
