Former Chilean President Sebastian Pinera is thanking supporters after he easily won the country's presidential runoff election Sunday.

Left-winger Alejandro Guillier conceded and congratulated his opponent on his win and his return to the presidency after a four-year gap.

It is a marked move to the right for the country, which is currently led by socialist President Michelle Bachelet. She had backed Mr Guillier.

About 14 million were eligible to vote in the ballot, including Chileans living abroad for the first time.
