On 7 October 2016, Santos was announced as recipient of the Nobel Peace Prize, for his efforts negotiating a peace treaty with the FARC-guerrilla in the country, despite his defeat in the referendum held over the deal, where the "no" campaign led by Uribe's party Democratic Center won. The Colombian government and the FARC signed a revised peace deal on 24 November and sent it to Congress for ratification instead of conducting a second referendum. Both houses of Congress ratified the revised peace accord on 29–30 November 2016, thus marking an end to the conflict. The treaty brought deep divisions and polarization in the country, which questions its legitimacy. Juan Manuel Santos has been named as one of Time magazine's 100 most influential people. However, Santos left office with one of the lowest levels of popular approval ever, and his successor was Uribe's new protégé, Iván Duque Márquez, a moderate critic of Santos' peace treaty with the FARC-guerilla.
