Image copyright ReutersSouth Korea's impeached president, Park Geun-hye, is due to find out whether she will be permanently removed from office.
Ms Park has been accused of colluding with a friend who allegedly pressured big companies to give money in return for government favours.
She has been suspended from official duties since parliament voted to impeach her in December.
Ms Park and her friend, Choi Soon-sil, both deny doing anything wrong.

If her dismissal is upheld, a presidential election will be held within 60 days. As long as she remains president, she is immune from prosecution.
