Out of 300 lawmakers, 204 voted to impeach the president on allegations of insurrection while 85 voted against.
Three abstained, with eight votes nullified.
Yoon is now suspended from office while South Korea’s Constitutional Court deliberates whether to uphold his removal.
Prime Minister Han Duck-soo steps in as the interim president.
The court now has 180 days to rule on Yoon’s future.
If it backs his removal, Yoon would become the second president in South Korean history to be successfully impeached.
South Korean PM vows to ‘ensure stable governance’ after Yoon impeached
South Korean Prime Minister Han Duck-soo on Saturday vowed to “ensure stable governance” after the country’s parliament voted to impeach President Yoon Suk Yeol.
“I will devote all my strength and efforts to ensure stable governance,” Han, who becomes the country’s interim leader in Yoon’s place, told reporters.
S. Korea’s Yoon: from rising star to impeachment
South Korean’s Yoon Suk Yeol rose from public prosecutor to the nation’s highest office in just a few years, but as president he staggered from scandal to scandal before plunging the country into crisis by declaring martial law.
The lurch back to South Korea’s dark days of military rule only lasted a few hours, and after a night of protests and high drama last week Yoon was forced into a U-turn.
But polls show a huge majority of citizens want him out and lawmakers voted Saturday to impeach him. He is now the third South Korean president to be impeached by parliamentary vote, and if upheld by the Constitutional Court would be the second to be removed from office.
This week Yoon had vowed to fight “until the very last minute” in a defiant public address in which he doubled down on claims the opposition was in league with South Korea’s communist enemies.
Born in dictatorship
Born in Seoul in 1960 months before a military coup, Yoon studied law and went on to become a star public prosecutor and anti-corruption crusader.
He played an instrumental role in Park Geun-hye, South Korea’s first female president, being impeached in 2016 and later convicted for abuse of power and imprisoned.
As the country’s top prosecutor in 2019, he also indicted a senior aide of Park’s successor, Moon Jae-in, in a fraud and bribery case.
The conservative People Power Party (PPP), in opposition at the time, liked what they saw and convinced Yoon to become their presidential candidate.
He duly won in March 2022, beating Lee Jae-myung of the Democratic Party, but by the narrowest margin in South Korean history.
Halloween to handbag
Yoon was never much loved by the public, especially by women — he vowed on the campaign trail to abolish the ministry of gender equality — and scandals have come thick and fast.
This included his administration’s handling of a 2022 crowd crush during Halloween festivities that killed more than 150 people.
Voters have also blamed Yoon’s administration for food inflation, a lagging economy and increasing constraints on freedom of speech.
He was accused of abusing presidential vetoes, notably to strike down a bill paving the way for a special investigation into alleged stock manipulation by his wife Kim Keon Hee.
Yoon suffered further reputational damage last year when his wife was secretly filmed accepting a designer handbag worth $2,000 as a gift. Yoon insisted it would have been rude to refuse.
His mother-in-law, Choi Eun-soon, was sentenced to one year in prison for forging financial documents in a real estate deal. She was released in May 2024.
Yoon himself was the subject of a petition calling for his impeachment earlier this year, which proved so popular the parliamentary website hosting it experienced delays and crashes.
‘You can sing!’
As president, Yoon has maintained a tough stance against nuclear-armed North Korea and bolstered ties with Seoul’s traditional ally, the United States.
Last year, he sang Don McLean’s “American Pie” at the White House, prompting US President Joe Biden to respond: “I had no damn idea you could sing.”
But his efforts to restore ties with South Korea’s former colonial ruler, Japan, did not sit well with many at home.
Yoon has been a lame-duck president since the opposition Democratic Party won a majority in parliamentary elections this year. They recently slashed Yoon’s budget.
In his televised address declaring martial law, Yoon railed against “anti-state elements plundering people’s freedom and happiness”, and his office has subsequently cast his imposition of martial law as a bid to break through legislative gridlock.
But to use his political difficulties as justification for imposing martial law for the first time in South Korea since the 1980s was absurd, an analyst said.
“Yoon invoked Article 77 of the South Korean constitution, which allows for proclaiming martial law but is reserved for ‘time of war, armed conflict or similar national emergency’, none of which appears evident,” Bruce Klingner, a senior research fellow at the Heritage Foundation, told AFP.
“Yoon’s action is a damning reversal to decades of South Korean efforts to put its authoritarian past behind it,” he said.
