The president of what country won the 2016 Nobel Peace Prize?

Juan Manuel Santos Calderón is a Colombian politician and the President of Colombia, in office since 2010.

On October 7, 2016, Santos was announced as recipient of the Nobel Peace Prize, for his efforts negotiating a peace treaty with the FARC-guerilla in the country, despite the unsuccessful referendum held over the deal. The Colombian government and the FARC signed a revised peace deal on November 24 and sent it to Congress for ratification instead of conducting a second referendum. Both houses of Congress ratified the revised peace accord on November 29–30, 2016, thus marking an end to the conflict. Juan Manuel Santos has been named as one of Time magazine's 100 most influential people.
