The main opposition Democratic Party of Korea (DPK) and its supporters held a massive rally in central Seoul on Saturday, lashing out at the Yoon Suk Yeol government for what they called the mishandling of state affairs and demanding a special counsel probe into first lady Kim Keon Hee.

DPK leader Lee Jae-myung and around 100,000 party members and supporters — a count claimed by the party — gathered near Gwanghwamun Square and staged a rally, according to police and party officials.

The protest was the fifth of its kind.

The participants called on Yoon to accept a bill for a special counsel probe into Kim for her alleged involvement in a stock manipulation scheme, the alleged interference in election nominations through a broker and the acceptance of a luxury bag, among other things.

Yoon vetoed the bill, Tuesday, the third time he has rejected the DPK-led bill.

"Judging Yoon Suk Yeol and punishing Kim Keon Hee ... are all a battle for democracy," Rep. Kim Min-seok told supporters.

The party then joined civic groups protesting the government and held a candlelight vigil.

Conservative civic groups also held a rally in support of the government, but no physical clashes were reported, according to officials. (Yonhap)
