In 1960 and 1961 he was a Plebiscite Supervisor in the Southern Cameroon. He was called to the Bar at the Middle Temple in July 1962, and specialised in libel until 1979. As a barrister, he defended Time Out magazine, owned by Playboy Publications, Inc., in 1973, when they had accused Fiona Lewis, an actress, of being involved with South American revolutionaries. She was awarded damages. The following year, he represented The Spectator magazine who had libelled publishers Jonathan Cape, suggesting they were in financial difficulties, and won a similar outcome in that case. In 1975 he was more successful in representing Marcia, Lady Falkender, who was falsely accused of forging the signature of her boss, former Prime Minister Harold Wilson. She was paid damages and costs. In 1977, Adeane represented Marlene Dietrich in a libel case brought by producer Alexander Cohen for breach of contract, as a disreputable performer. Adeane was appointed Private Secretary and Treasurer to the Prince of Wales in May 1979 to succeed David Checketts. Prince Charles and Edward Adeane shared a passion in angling on the River Test near Stockbridge, Hampshire. They were members of the Houghton Fishing Club, where Adeane continued to fish right up until his last days. On the engagement of Lady Diana Spencer and the Prince, she was due to arrive at Albany House, where Adeane had a barrister's set. The staff expected octogenarian Lady Diana Cooper, but were bemused to find a much younger lady arrive in her Mini Metro and park perfectly. Princess Diana had a nervous start in a royal household, where she dismissed almost all of the staff. Adeane was made the Princess's Treasurer in 1981 on their marriage. Adeane was granted the additional appointment as private secretary to the Princess in 1984, following Oliver Everett's resignation. The alleged trouble started during the 1983 royal tour of Australia and New Zealand, when the Princess first expressed concern at leaving her children behind in London. The Daily Mirror reported her calling Adeane a "fuddy-duddy". When Adeane tried to plan a tour of Australia in 1984, he was accused of trying to manipulate State elections in Victoria for political purposes. In attempting to distance the Premier, Adeane was quoted in the Daily Mirror and other newspapers. Adeane resigned after disagreements and accusations that he was taking decisions without consulting the prince, and being too much of the 'old school tie' about him. However Adeane found that the prince invariably did the opposite of what he was advised. An almost unprecedented state of affairs materialised on 19 March 1985, when the press were invited into Buckingham Palace to discuss relations. Evidently the last straw for Adeane he resigned on 31 March 1985. He was Equerry to the Prince of Wales 1979–1981, and was an Extra Equerry from 1985. He represented the Prince at Royal Household memorial services – and returned to practice at the Bar. His departure commenced a period of instability in royal sinecures, including the Queen's annus horribilis, with several private secretaries coming and going in short order. He was replaced by Sir John Riddell.
Personal life
Adeane never married and is survived by companion, Brent Snape. Adeane was appointed a CVO in 1985. He died on 20 May 2015.
