During the Second World War, Bligh served in the Royal Navy in the North Atlantic, the English Channel and the Mediterranean, and was twice wounded. He was awarded the DSC and bar and the DSO, and was appointed an OBE. Bligh joined the Civil Service in 1946 as an assistant principal in the Treasury, and was rapidly promoted, reaching the rank of under-secretary in 1959. That year he was appointed principal private secretary to the prime minister, Harold Macmillan, whom he served until the latter's resignation in October 1963. Bligh then served Macmillan's successor, Alec Douglas-Home in the same capacity, until Douglas-Home's defeat in the 1964 British general election.[1]
As the prime minister's principal private secretary, Bligh was peripherally involved in the Profumo affair of 1963, a scandal which brought about the resignation of John Profumo as Secretary of State for War and destabilised the government. Before the affair broke, Bligh had been advised of the possibility that Profumo had compromised national security through a sexual affair with a 19-year-old showgirl, Christine Keeler, who was a known associate of the society osteopath Stephen Ward, a suspected Soviet sympathiser. Bligh interviewed Profumo, who denied any wrongdoing but asked if he should resign to avoid embarrassing the government. He was advised that he should not.[3] Later, when the affair was unravelling, Bligh met Ward, who by then, at the Home Office's instigation, was under police investigation regarding possible vice charges. Ward asked Bligh if there was anything that could be done to halt the investigation, which was proving ruinous to his practice. Bligh took no action.[4] In June 1963 when the scandal reached its climax, Macmillan being absent in Scotland it was to Bligh that Profumo first confessed his guilt, and it was Bligh who transmitted the contents of Profumo's resignation letter to the prime minister.[5]
