big mouth", Wallace said. Margaret did not reveal this publicly until an interview and subsequent biography with Nigel Dempster in 1977. Margaret met the photographer Antony Armstrong-Jones at a supper party in 1958. They became engaged in October 1959. Armstrong-Jones proposed to Margaret with a ruby engagement ring surrounded by diamonds in the shape of a rosebud. She reportedly accepted his proposal a day after learning from Townsend that he intended to marry a young Belgian woman, Marie-Luce Jamagne, who was half his age and greatly resembled Margaret.

Separation and divorce Both parties in the marriage regularly engaged in extra-marital relationships. Antony had a series of affairs, including with long-term mistress, Ann Hills, and Lady Jacqueline Rufus-Isaacs, daughter of the 3rd Marquess of Reading. Anne De Courcy’s 2008 biography summarises the situation with a quote from a close friend: "If it moves, he'll have it." Reportedly, Margaret had her first extramarital affair in 1966, with her daughter's godfather Anthony Barton, a
