Earl Spencer has promoted his new memoir about his sister Princess Diana, which contains controversial allegations about King Charles. The most significant claim is that Charles allegedly told him "We will forget her soon enough" shortly after Diana's death. This sparked an unprecedented rebuke from Buckingham Palace, which questioned the accuracy of Spencer's account and suggested grief may have affected his memory.

The 62-year-old Earl appeared on ITV's Lorraine programme to defend his claims, describing the Palace's response as "classic gaslighting" and insisting he stands by the truth. The book also alleges Charles opposed Spencer's objections to Prince William (then 15) and Prince Harry (then 12) walking in their mother's funeral procession in 1997. Spencer maintains the memoir was intended to celebrate Diana rather than attack the King, though he acknowledges other people may not come across favourably in the account.
