Sinha was also the President of the BPCC in 1936 with A.N. Sinha as his deputy, a member of its working committee and in fact, Sinha and A.N. Sinha were the life and soul of the Provincial Working Committee and of the Congress organisation in the state for over thirty years. This long period of service at the help of the state is a proof not only of the great popularity and confidence which he enjoyed in the party but it symbolises also his great qualities as a co-ordinator between party and government.
