Butler was given his first ministerial job as Under-Secretary of State for India (29 September 1932) when Lord Lothian resigned along with the rest of Herbert Samuel's Official Liberals over the National Government's abandonment of free trade. At 29, he was the youngest member of the government. At the end of March 1933, Butler spoke for the Government in the House of Commons, calling for a Joint Select Committee of Both Houses to examine the recent White Paper and make proposals for an India bill. Butler was active speaking in the country on behalf of the Union of Britain and India, a front organisation funded by Conservative Central Office and launched on 20 May 1933. Butler faced significant opposition from Conservative activists in his constituency. Baldwin replaced Ramsay MacDonald as Prime Minister (7 June 1935) during the Third reading of the bill. In the resulting reshuffle Hoare became Foreign Secretary and was succeeded as India Secretary by Lord Zetland, so Butler had to steer the final stages of the bill which became the Government of India Act 1935 through the House of Commons. Butler continued as Under-Secretary for India for the rest of Baldwin's government (1935–37).
