Embattled South Korean President, Yoon Suk Yeol on Friday was ousted by the Constitutional Court, which upheld parliament's impeachment motion over his short-lived imposition of martial law last year that triggered the country's worst political crisis in decades.

According to the country's constitution, with Yoon's removal, a presidential election is required to take place within 60 days.

However, Prime Minister Han Duck-soo will continue to serve as acting president until the new president is inaugurated.

Acting Chief Justice Moon Hyung-bae said Yoon violated his duty as president by taking actions that were beyond the powers given to him under the Constitution, and the effect of his actions was a serious challenge to democracy.

He added that by declaring martial law, Yoon created chaos in all areas of society, the economy, foreign policy.

β€œYoon committed a grave betrayal of the people's trust who are the sovereign members of the democratic republic,” he said.

Meanwhile, thousands of people at a rally calling for Yoon's ouster, including hundreds who had camped out overnight, erupted into wild cheers on hearing the ruling, chanting β€œWe won!”

The ruling caps months of political turmoil that have overshadowed efforts to deal with the new administration of US President Donald Trump at a time of slowing growth.
