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. 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. 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. ==Private life==
