●  In November 1927, the British government appointed the Simon Commission to report on India's constitutional progress for introducing constitutional reforms, as promised.

Reason why Simon commission was boycotted:

●  It was opposed by Nehru, Gandhi, Jinnah (Pakistan), the Muslim League and Indian National Congress because it contained seven members of the British Parliament but no Indians.

●  Indians saw it as a violation to their right of self determination and insult to their self respect.

●  However it was supported by B R Ambedkar and Periyar E. V. Ramasamy.

●  Prominent Indian nationalist Lala Lajpat Rai led a protest in Lahore. He suffered a police beating during the protest, and died of his injuries on 17 November 1928.
