With a week to go before South Korea's general election, a major local news outlet suggests the main opposition Democratic Party is in the lead.

South Korea holds general elections every four years. Voters will cast their ballots next Wednesday.

The vote is seen as a midterm assessment of the administration of President Yoon Suk-yeol, who has been in office for two years.

Leaders of different parties have been seen visiting electoral districts where the races are too close to call.

Ruling People Power Party interim leader Han Dong-hoon addressed voters in the central city of Chungju on Wednesday.

He described the current situation as "like walking on thin ice."

He added securing victory in closely fought regions will make the difference for the PPP.

Meanwhile, the head of the main opposition Democratic Party, Lee Jae-myung attended a ceremony marking the Jeju April 3 Uprising on the southern island, in which islanders were persecuted by conservatives at the time.

Following the event, he branded the ruling PPP as "descendants" of the incident.

A report by Yonhap News Agency on Wednesday interviewed political experts and others. It reported a majority of experts put the Democratic Party in the lead over the PPP.

At the same time, some Democratic Party candidates are under media scrutiny.

One candidate has been accused of making discriminatory remarks about women, while another stands accused of illegally taking out massive loans.
