Queen Elizabeth II had dismissed King Charles III’s nanny over a "special pudding".
This emerged in royal author Bryan Kozlowski's book Long Live the Queen! 13 Rules for Living from Britain’s Longest Reigning Monarch.
He penned : "In 1956, the Queen sent the nursery a simple request that King Charles, then aged eight, be given a special pudding she thought he might like.
"[The nanny] refused, crossed the dessert from the menu, and incurred the Crown's wrath."
"Nobody crosses out the Queen's request."
