In 1974, Wilson had a health scare over a racing heart complaint, but "I told the press, who believed me when I said that Harold had the flu," Haines recalled in 2004. "We had an economic crisis and we had a majority of three", he explained. In
Glimmers of Twilight (2003), Haines said that Wilson's doctor
Joseph Stone offered to murder
Marcia Falkender, the head of Wilson's political office, after she attempted to blackmail Wilson over an affair they had twenty years earlier. The BBC, in an out-of-court settlement with Falkender, paid her £75,000 after these claims were repeated in
The Lavender List, a drama documentary written by
Francis Wheen and broadcast in 2006. The allegations relating to Stone were repeated in the BBC's documentary
The Secret World of Whitehall (2011). Not long after Wilson's resignation as Prime Minister, Haines published a book
The Politics of Power about his experience of British political life. Attention mainly concentrated on two chapters about Marcia Williams (now Falkender) and her influence. Haines said that Williams' troublesome presence had been the real cause of Wilson's resignation. The Labour MP
Brian Sedgemore considered that
The Politics of Power was an interesting account, but the chapters about Marcia Williams were the weakest in the book. In a 2010 interview, Haines said that in the aftermath of the
February 1974 general election, Harold Wilson had planned to discredit
Liberal leader
Jeremy Thorpe by exposing Thorpe's
relationship with Norman Scott in the event of the
Conservative government reaching an agreement with the Liberals that would have permitted it to remain in power. Around the same time, Haines said that he had turned down a
peerage from Wilson in the
1976 Prime Minister's Resignation Honours in part, he said, because he did not wish to be awarded one in a list also consisting of
Joe Kagan and
Eric Miller, who were suspected of criminal activity at the time. In 2024, Haines revealed that Wilson had had an affair with Haines' deputy Janet Hewlett-Davies during his final two years as Prime Minister. Hewlett-Davies died aged 85 in October 2023. ==Later career==
