During the remainder of World War II, the BLPI influenced the trade union and student movements in several cities. Significant membership was recorded among tramway workers, as well as workers of the Buckingham and Carnatic Mills. The BLPI notably played a major role in the Quit India movement. It produced leaflets and posters giving unconditional support to the movement. It went even further, calling for the troops to revolt. The objective was ultimately for the British expulsion from India. Their efforts to direct the Quit India disruption into a revolutionary one brought significant reprisals, with members forced into hiding. The BLPI was the only political party to give unconditional support to the Royal Indian Navy mutiny.
