2010 Colombian presidential election

Presidential elections were held in Colombia in 2010. They took place under a two-round system, with an initial vote held on 30 May and a second poll held three weeks later on 20 June. A referendum proposal that would have allowed incumbent President Álvaro Uribe the opportunity to run for a third term was rejected by the Constitutional Court of Colombia in a 7–2 ruling on 26 February 2010. Because no candidate received a majority (more than one-half) of the votes cast in the 30 May poll, the candidates with the two highest vote totals competed in a runoff election on 20 June: Juan Manuel Santos of the liberal-conservative Social Party of National Unity which unites supporters of former President Uribe, and Antanas Mockus from the Green Party. Santos won the election with 69% of the votes.
