Opposition leader Lee Jae-myung appeared in court Tuesday for a hearing to decide whether to issue an arrest warrant for him over corruption charges, the biggest crisis yet for the former presidential candidate.

Leaning on a walking stick, the frail-looking Lee walked slowly and unsteadily as he entered the court without answering a barrage of questions from reporters.
