Gabriel Boric is the youngest person to be elected president in the country's history.
The New York Time reported that Boric, a lawmaker and former student protest leader, included promises of radical reforms on inequality into his platform, including raising taxes on the rich, expanding the country's social safety net, and drafting a new Constitution.
Boric said during a video call with Piera that he would be the president of all of the country.

His opponent, a right-wing candidate, conceded 90 minutes after the polls closed. Both Boric and Kast are members of political parties that have never been represented in the government.
Boric is the president-elect of Chile and deserves all our respect and constructive collaboration, said Kast.
