Kim Dae-jung, the former South Korean president famous for his "Sunshine Policy" of engagement with rival North Korea has died, hospital officials in Seoul have said.
The 85-year-old reportedly suffered heart failure on Tuesday after weeks of treatment for pneumonia.
Kim, popularly known as "DJ", served as South Korea's president from 1998 to 2003.
He won the Nobel Peace Prize for brokering the landmark 2000 summit between the leaders of North and South Korea in Pyongyang.
The summit was the first ever meeting between the leaders of the two Koreas.
Kim was also a towering figure in South Korea's struggle for democracy against the country's early authoritarian leaders.
For much of his life he walked with a limp that was the result of injuries suffered in an assassination attempt in the 1970s when a truck rammed his car off a road.
