-It was a striking end for South Korean President Park Geun-hye. "She had one more year left as "president" but, now she's been ousted, she will be investigated as a common criminal", the North Korean mouthpiece Korean Central News Agency (KCNA) said a brief dispatch.
Ms Choi is accused of using her presidential connections to pressure companies to give millions of dollars in donations to non-profit foundations she controlled.
Park's impeachment by parliament last December was preceded by mass protests which saw hundreds of thousands of people pack the streets of Seoul for several months, calling for her removal.
The ouster of President Park Geun-hye will trigger a May 9 election that is expected to install a leader who is more skeptical of Washington's policies in the region and more sympathetic to North Korea and China.
They carried flags and candles and cheered jubilantly, a day after the Constitutional Court removed her from office over a corruption scandal which had consumed the nation for months.
Supporters of South Korean President Park Geun-hye watch a live broadcast of a Constitutional Court decision on a smart phone during a rally opposing her impeachment near the Constitutional Court in Seoul, South Korea, on March 10, 2017. Anti-Park protesters celebrated by marching in the streets near the presidential Blue House, carrying flags, signs and an effigy of Park dressed in prison clothes and tied up with rope.
China's 2017 Defence Budget To Increase By 7%
Ms Fu dismissed concerns that China posed a threat to the region with its expanding military. President Donald Trump will formally submit his first budget to Congress later this month.
Feb 25, 2013: Park is sworn in as the first female president of South Korea, promising an era of hope.
Ms Park is the daughter of Korean general Park Chung-hee, who is credited as setting the country towards industrialisation and democracy.
This follows the December move when she was suspended in December by a legislative impeachment vote. Investigators say Park abused her power by entrusting government decisions to a secret adviser, Choi Soon-sil, and took part in extorting bribes from major conglomerates, including Samsung and Hyundai.
Since she's now no longer in power, prosecutors can summon, question and possibly arrest her. Lee Jae-yong, vice chairman of Samsung Electronics, now remains in custody following his arrest on February 17 over bribery charges. He is indicted on charges including pledging $US37.24 million in payments to Ms Choi.
If six out of the eight justices uphold the motion, Park will be forced out of office.
