Kathmandu: Sushil Koirala, a former Nepalese prime minister and leader of nation's largest political party, has died in Kathmandu. He was 78.
His doctor, Karbir Nath Yogi, said Tuesday that Koirala died due to complications from pneumonia and respiratory failure.
Koirala was a key figure in adoption of Nepal's new constitution last September with overwhelming support in the Constitution Assembly.
Koirala spent his life in politics fighting for democracy in Nepal and was one of the leading activists in protests in 2006 that ended a centuries-old monarchy system and turned Nepal into a republic.
He never married and spent at least six years in prison and years in exile in neighboring India.
His body will be kept at the party's headquarters in Kathmandu.
