Former Samajwadi Party leader Amar Singh has died after battling an illness at the age of 64.
He had gone to a hospital in Singapore in March for surgery in a kidney-related illness. He had undergone a kidney transplant in 2011.
Amar Singh was a key leader in the Samajwadi Party at a time when the party moved to support the Congress-led United Progressive Alliance (UPA) government in 2008.
