Imphal, July 13: Health condition of Octogenarian Politician Rishang Keishing has improved, doctors at RIMS says. Mr. Keishing had served the state as Chief Minister for many terms. He is 98 and his mental condition is normal. Manipur Chief Minister N. Biren Singh and Works Minister Th. Bishwajit Singh yesterday visited the former Chief Minister at RIMS yesterday evening. “Keishing is undergoing dialysis and his condition is not serious,” the doctors said today.
