South Korea's former first lady Kim Keon Hee will spend her first day in jail on Wednesday in a cell much like the one her husband and ex-President Yoon Suk Yeol occupies as prosecutors pursue the once high-flying couple in a widening criminal probe.

Kim Keon Hee, accused of accepting Chanel bags and other items as bribes, is the only former first lady in the country to have been put behind bars. Her husband has also been jailed on insurrection charges.
