Butler helped to precipitate Macmillan's brutal "Night of the Long Knives" reshuffle by leaking to the "Daily Mail" on 11 July 1962 that a major reshuffle was imminent. He himself referred to it as the "Massacre of Glencoe". Macmillan later told Selwyn Lloyd (1 August) that he thought Butler had been planning to split the party over EEC entry. In the reshuffle Butler lost the Home Office (although he kept the Central Africa Department) but at last received the formal titles of Deputy Prime Minister and First Secretary of State, though Rodney Brazier, while agreeing that Butler was First Secretary of State and that he deputised, including for six weeks during Macmillan's 1958 tour of the Commonwealth, denies that he was ever formally appointed Deputy Prime Minister. At this point Macmillan told him that he was still his most likely successor as Prime Minister.
