Campaigning for South Korea’s Presidential election has began, in what is expected to be the tightest race in twenty years.

The ruling Democratic Party’s Lee Jae-myung began his campaign with a visit to a shipping control tower in the southeastern port city of Busan.

The conservative People Power Party’s Yoon Suk-yeol, Lee’s main rival, started his bid for office at the Seoul National Cemetery.

Opinion polls suggest voters are looking for a President who can address polarized politics and tackle corruption, as well as deal with soaring housing prices and deepening inequality.
