Derby formed a minority government in February 1852 following the collapse of Lord John Russell's Whig Government. In this new ministry, Benjamin Disraeli was appointed Chancellor of the Exchequer. With many senior Conservative ministers having followed Peel, Derby was forced to appoint many new men to office—of the Cabinet, only three were pre-existing Privy Counsellors. When the aged Duke of Wellington, by then very deaf, heard the list of inexperienced cabinet ministers being read aloud in the House of Lords, he gave the government its nickname by shouting "Who? Who?". From then this government would be known as the "Who? Who?" ministry.
