Former South Korean Prime Minister Lee Wan-koo died at the age of 71. Lee served as prime minister for a brief period between February and April in 2015 under the then-President Park Geun-Hye.
Lee was diagnosed with multiple myeloma, a type of blood cancer, in 2012 but recovered after a stem cell transplantation.
The disease, however, recurred in 2016, forcing him to be hospitalized again.
Regarded as a senior politician in Chungcheong Province, Lee entered politics in 1995 and was elected to three terms of parliament for the conservative New Korea Party and the United Liberal Democrats, and also held key positions in both parties.
In 2006, he was elected governor of South Chungcheong Province but resigned in 2009 in protest of Lee Myung-bak’s administration plan for Sejong City.
