In 1970, Man Singh had an accident while playing polo in Cirencester, England. He died later the same day. He was survived by his four sons. He was succeeded as Maharaja of Jaipur and head of the Kachwaha clan by his eldest son, Maharaja Sawai Bhawani Singh of Jaipur. Following his death Indira Gandhi was finally able to repress the power of India's former rulers in democratic India as they formed a large bulk of her opposition party, the Swatantra party.
