Srivastava was hospitalized on August 10 after he collapsed while working out in a gym, television news channels reported. He had to undergo an angioplasty the same day.

He was rushed to the All India Institute of Medical Sciences (AIIMS) and underwent angioplasty. Since then, he was on the ventilator and never gained consciousness.

"I got a call from the family about half-an-hour ago saying he is no more. It is really unfortunate news. He was fighting in the hospital for over 40 days," Dipoo Srivastava told PTI.

Raju Srivastava was declared dead at 10.20 am, according to hospital sources.

Prime Minister Narendra Modi paid tribute to the popular comedian, saying he "brightened our lives with laughter, humour and positivity".

Srivastava, who made a mark as a stand-up comic and later entered politics, died after more than 40 days in hospital. He had joined the BJP in 2014.
