Chileans face stark choice in vote for president after two years of unrest

Progressive former student leader Gabriel Boric and far-right Jose Antonio Kast are neck-and-neck ahead of Sunday's first round

Voters in Chile head to the polls on Sunday in a general election in which the two frontrunners for president offer starkly contrasting visions for the country's future after two years of street protests and political unrest.

Polls suggest that the progressive former student leader Gabriel Boric, 35, and the far-right candidate, Jose Antonio Kast, are neck-and-neck ahead of five other candidates - though neither seems likely to cross the 50% threshold needed to avoid a December runoff.
