Who was the co-founder of the Swaraj Party along with Motilal Nehru?

The Swaraj Party was founded in 1923 after the Non-Cooperation Movement was suspended by Mahatma Gandhi.
Many leaders felt the need for a new political strategy to continue the struggle against British rule.
Motilal Nehru and Chittaranjan Das (popularly known as Deshbandhu C.R. Das) co-founded the Swaraj Party.
Their aim was to enter the legislative councils set up by the British and obstruct colonial policies from within, while demanding self-governance (Swaraj).
The party played a crucial role in keeping the spirit of freedom alive during the 1920s.
So, the co-founder of the Swaraj Party along with Motilal Nehru was Chittaranjan Das.
