The son of a Nazi party member and an admirer of Pinochet, Kast built his campaign on a promise to expel tens of thousands of undocumented migrants

The ultra-conservative former congressman José Antonio Kast has been elected as Chile’s next president.

With more than 99% of polling stations counted, Kast took 58.16% of the vote, against 41.84% for the leftist Jeannette Jara, a former labour minister under the current president, Gabriel Boric.

Trump-inspired former congressman expected to succeed Gabriel Boric but compulsory voting could create volatility

Chileans will head to the polls on Sunday for a presidential runoff in which the favourite is a Donald Trump-inspired candidate who has pledged to build a wall along the country’s borders to keep migrants out.

José Antonio Kast, 59, an ultra-conservative former congressman who has built his campaign on a promise to expel tens of thousands of undocumented migrants, faces Jeannette Jara, 51, a former labour minister under the current centre-left president, Gabriel Boric, 39.
