Kim Min-Ki, the wife of South Korean President Moon Jae-in, took to Twitter on Tuesday to claim victory in her presidential election.
The 58-year-old former president was defeated in a runoff by incumbent Park Geun-hye, who has led the country for over four decades.
Park, who is the daughter of former South Korean leader Kim Il Sung, is currently serving a one-year prison sentence after being indicted in the hacking of Sony Pictures Entertainment, which she accused of selling confidential files to the US government.
“I congratulate President Moon and I congratulate the entire nation,” Kim said in her tweet.
Park’s opponent, former National Assembly speaker Nam Han-soo, has said she will seek a third term.
The election results also brought to an end an unprecedented presidential term in South Korea, with both candidates taking office just weeks apart.
