The front-runner among South Korea's likely presidential contenders is former opposition leader Moon Jae-in, who has flagged an overhaul of Seoul's policy on North Korea, suggesting he is in favour of more talks and would be prepared to meet Kim Jong Un if certain conditions were met.
The ruling instantly strips Park of her powers and also her immunity against prosecution.
Park was impeached by parliament in December over a major corruption and influence-peddling scandal that rocked the nation and prompted millions to take to the street to demand her ouster.
Eight judges from the Constitutional Court assembled on Friday to issue a verdict to remove Park from office over a corruption scandal. "The Constitution is a value everyone including the president must uphold and respect", she said.
Park's actions had "seriously impaired the spirit of. democracy and the rule of law", said constitutional court chief justice Lee Jung-Mi.
It's the worst time for South Korea President Park's impeachment because of the uncertainty and deterioration in the security situation on the Korean peninsula, according to Viktor Goa, Director of the China National Association of International Studies.
25 Oct, 2016: Ms Park makes her first public apology for giving Ms Choi access to draft speeches during the first months of her presidency.
Park is accused of colluding with Choi to extract money from the firms and letting the friend handle a wide range of state affairs, including the nomination of cabinet members.
According to the same news agency, two pro-Park protesters died from injuries suffered in the clashes, including a 72-year-old man, who was found bleeding from his head near the Constitutional Court.
But the judges dismissed some charges, including accusations Ms Park had infringed on freedom of the press by creating a media blacklist of cultural figures, and criticism of her response during the 2014 Sewol ferry disaster.
Nov 29, 2016: In her third televised apology, Park asks parliament to decide how and when she could give up power over the scandal.
Park met with her Cabinet after the impeachment vote and refused to resign. Due to Park's suspension her post was temporarily assumed by Prime Minister Hwang Kyo-ahn.
He and Samsung have denied wrongdoing.
A presidential spokesman yesterday said Ms Park would continue to reside in the presidential Blue House and no date has been fixed for her to move to her private residence in the upscale Gangnam district.
She has been charged with various offences, including abuse of authority, coercion, attempted coercion and attempted fraud, leading to the wider investigation.
