Singh died last night at Keshavkunj in Delhi and was cremated today at Nigambodh Ghat here.
Delhi BJP president Satish Upadhyay said Singh's life and work as a pracharak were spread over seven decades.
"In 1943, he qualified for Air Force Officer rank but he rejected the job in British Army and instead joined RSS as a pracharak. In his 70 years of work in RSS, he held several responsibilities. Singh was like a father figure for most of the present generation working in BJP and other bodies related to RSS," he said.
