Another source said: “Piers’ intervention couldn’t have come at a worse time for Spencer. The Palace had already challenged his recollection involving the King, and suddenly there was an entirely separate claim where Spencer himself accepted he’d made an error.
“Charles and William’s approach has essentially been to get on with their jobs. The feeling is that responding to every allegation would only give the book more oxygen.”
Charles was in Peterhead, Aberdeenshire, meeting Sea Cadets, the RNLI and organizations involved in the region’s energy sector as Spencer’s memoir reached bookstores.
Unveiling a plaque, Charles said: “I’m sorry it’s taken so long to turn up here. I’m delighted.”
William similarly maintained his public schedule, visiting ActOne, an independent cinema in Acton, west London, in his role as BAFTA president.
When asked by a reporter how he felt about his uncle’s memoir, William did not respond.
Spencer has meanwhile said Prince Harry, 42, is “completely fine” with the book, which he maintains was written as a personal tribute to his sister rather than an attack on the monarchy.
