Park is suspected of soliciting 59.2 billion won ($52 million) in bribes for herself and Choi, an allegation that could have her imprisoned for a minimum 10 years to life if convicted.

The start of her trial could highlight the nadir of Park's fate, which has drastically changed over the course of only a few months.

She was in the country's highest elected office less than eight months ago when her corruption allegations first surfaced in October.

Despite her repeated denials, it has been a steady roll down hill for her ever since.

The parliament voted to impeach Park in December, marking the second impeachment of an incumbent president in the country's history.

And on March 10, the Constitutional Court upheld the parliamentary impeachment, making Park the first South Korean leader to ever be removed from office.

On Tuesday, Park became the third president in the country's history to face a criminal trial.

On the opposite side of the spectrum is former President Roh Moo-hyun, who had largely remained disgraced and accused of corruption since he took his own life eight years ago Tuesday amid a prosecution investigation on corruption allegations involving his family members.

An annual memorial service again marked his tragic death in his native hometown of Bongha, a small village located some 450 kilometers southeast of Seoul in South Gyeongsang Province.

What made this year's service special was the attendance of President Moon Jae-in, apparently reinstating the late president's honor.

The president was also joined by a series of political leaders such as National Assembly Speaker Chung Sye-kyun, as well as his top presidential aides, including chief of staff Im Jong-seok.

When asked to comment on former President Park's trial, however, officials at the presidential office Cheong Wa Dae said they had nothing to say. (Yonhap)
