South Korea’s constitutional court upheld the impeachment of President Park Geun-Hye, removing her from office over a graft scandal involving big business that has gripped the country for months.

According to the constitution, park becomes South Korea’s first democratically elected leader to be forced from office. A presidential election will be held in 60 days.

The ruling to uphold Parliament’s December 9 vote to impeach park over an influence-peddling scandal is the most dramatic twist in a political crisis that has gripped the country for months.

The political crisis has come at a time when rival North Korea is pushing ahead with its missile program and tension is brewing with China over a U.S. Missile-Defense system being deployed in South Korea.
