South Korea’s former Prime Minister Lee Wan-koo on Friday made his first public appearance in 140 days since his resignation amid bribery allegations in April, to attend a trial for graft charges at the Seoul Central District Court in southern Seoul.

Lee had been accused of accepting illegal campaign funds worth 30 million won ($28,000) from the late businessman Sung Woan-jong for the 2013 by-elections, on April 4 that year, at his campaign office in Buyeo, South Chungcheong Province. He was indicted without detention in July, about three months after his resignation.

Sung, a construction mogul and former lawmaker, was found dead on April 9 in an apparent suicide at a mountain in northern Seoul. Hours before he committed suicide, he claimed that he had handed illegal funds to Lee, as well as seven other figures, in a phone interview with a local daily.
