Presidential elections were held in the Republic of the Congo on 12 July 2009. Long-time President Denis Sassou Nguesso won another seven-year term with a large majority of the vote, but the elections were marred by accusations of irregularities and fraud from the opposition; six opposition candidates chose to boycott the elections.
