Explanation:

'Gandhi-Irwin Pact' was a political agreement signed by Mahatma Gandhi and Lord Irwin, the then Viceroy of India, on 5 March 1931 before the second Round Table Conference in London. Before this, Lord Irwin, the Viceroy, had announced in October 1929 a vague offer of 'dominion status' for British India in an unspecified future and a Round Table Conference to discuss a future constitution. The second Round Table Conference was held from September to December 1931 in London.
