SEOUL, Nov 19 (Reuters) - South Korea's main opposition leader Lee Jae-myung was indicted on Tuesday on charges alleging he used more than 100 million won ($71,900) of public funds for personal purposes when he was a governor, Yonhap News Agency reported.

Lee, chair of the Democratic Party, is already facing four other trials including for bribery and other charges mostly tied to a $1 billion property development scandal. His legal battles have cast a cloud over his political fate and could jeopardise his expected bid to contest the next presidential race.

Prosecutors indicted Lee on breach of trust charges, accusing him of misusing some 106 million won in taxpayers' money during his 2018-21 stint as governor of Gyeonggi Province, just south of Seoul, according to Yonhap.

The charges also include accusations that he allowed his wife Kim Hye-kyung to use a government vehicle for private reasons while labelling it as official usage, Yonhap said, citing the Suwon District Prosecutors' Office, which filed the charges.

Funds were also spent to pay for pricey meals, groceries or laundry for Lee's family, but documented as expenses for meetings with public employees or overtime pay, Yonhap said.

Lee, who narrowly lost to President Yoon Suk Yeol in the 2022 election and is widely expected to seek to run again in 2027, has not publicly commented on the latest indictment, but has previously denied any wrongdoing and described other charges against the couple as "political retaliation."

The Democratic Party on Tuesday condemned the indictment as "farfetched" and a "scheme to kill the president's political foe."

Calls to the Suwon District Prosecutors' Office were not answered.

Breach of trust is punishable by 10 years in prison or a fine of up to 30 million won.

Any final prison sentence or a fine of 1 million won or more would strip him of his seat in parliament and his right to run in any elections for the next five years.

The ruling People Power Party said the case once again raised the question whether Lee was qualified to hold public office.

In a related case, a district court last week fined Kim Hye-kyung 1.5 million won for violating election law by offering a meal to several politicians' spouses using Gyeonggi provincial funds after Lee launched his presidential bid in 2021.

On Friday, Lee was convicted for violating election law and sentenced to a one-year prison term suspended for two years. Lee said that he would appeal.
