A year later, the ministerial team at the Treasury resigned en masse; Derick Heathcoat-Amory became the new Chancellor of the Exchequer, replacing Peter Thorneycroft and Simon was promoted to become Financial Secretary to the Treasury, replacing Enoch Powell. Simon held this second office for only one year, being appointed Solicitor-General in 1959 to replace Sir Harry Hylton-Foster on his election as Speaker of the House of Commons; meanwhile, Sir Reginald Manningham-Buller was Attorney General. Simon was rewarded on taking this third office with a knighthood, and became a Privy Councillor in 1961.
