General elections were held in Argentina on 25 October 2015 to elect the President and National Congress, and followed primary elections which were held on 9 August 2015. A second round of voting between the two leading candidates took place on 22 November, after surprisingly close results forced a runoff. On the first runoff voting ever held for an Argentine Presidential Election, Buenos Aires Mayor Mauricio Macri narrowly defeated Front for Victory candidate and Buenos Aires Province Governor Daniel Scioli with 51.34% of votes. He took office on 10 December, making him the first freely elected president in almost a century who was not either a Radical or a Peronist.
