Merlin Hay's grandfather was Josslyn Hay, the 22nd Earl of Erroll, who was murdered in Nairobi on 24 January 1941. No one was ever convicted of the murder, although Sir Jock Delves Broughton, (grandfather of Tessa Keswick director of the Centre for Policy Studies) was tried and stood trial and was acquitted, he committed suicide the following year. His wife had been having a high profile affair with Josslyn Hay. A book published in 2000 claims that Hay was actually murdered as part of an MI5 plot according to a review of the controversial book:
- At the time of his death, Erroll was the Assistant Military Secretary of Kenya and, at one stage, he had been a member of the British Union of Fascists. Trzebinski (the author) claims to have uncovered evidence that Erroll was targeted for assassination by the War Office on the grounds that he was a security risk. She points out that Erroll was murdered on the eve of the Abyssinian campaign in which British troops invaded Kenya's Italian-occupied neighbour. Other sources have suggested that he actively sold secrets to Mussolini's forces and was earmarked to be gauleiter of Kenya if an Italian invasion succeeded.
