On 8 June 2009, President Omar Bongo died of cardiac arrest at a Spanish hospital in Barcelona, ushering in a new era in Gabonese politics. In accordance with the amended constitution, Rose Francine Rogombé, the President of the Senate, became Interim President on 10 June 2009. The first contested elections in Gabon's history that did not include Omar Bongo as a candidate were held on 30 August 2009, with 18 candidates for president. The lead-up to the elections saw some isolated protests, but no significant disturbances. Omar Bongo's son, ruling party leader Ali Bongo Ondimba, was formally declared the winner after a 3-week review by the Constitutional Court; his inauguration took place on 16 October 2009.
