South Korea's opposition leader, Lee Jae-myung, has been convicted of violating election law in a case stemming from 2022.

Upbit, South Korea's largest crypto exchange, is under scrutiny for allegedly approving a significant number of accounts without proper identification verification.

Lee, who faces three other criminal trials, vowed to appeal, and it remains unclear whether the Supreme Court will decide on any of the cases before the presidential vote in 2027.

A South Korean court handed the country's opposition leader a suspended prison sentence Friday for violating election laws -- a ruling that may prevent him from running in the next presidential election.
