Liberal candidate wins South Korea's presidential election

Liberal candidate Moon Jae-in has declared victory in South Korea's presidential election after his two major rivals conceded defeat.

The election sets up the country's first liberal rule in a decade.

It follows months of political turmoil caused by ousted president Park Geun-hye's corruption scandal.

The concessions by conservative Hong Joon-pyo and centrist Ahn Cheol-soo came after exit polls forecast that Mr Moon would win.
