SANTIAGO (Reuters) - Chile will go to the polls to elect a new president on Sunday, a stark choice between leftist former student protest leader Gabriel Boric and ultra-conservative Jose Antonio Kast.

After a fragmented first-round vote, both candidates have shifted towards the center to attract moderate voters, though still offer wildly different views for the future of the copper-rich Andean nation of some 19 million people.
