Charles Spencer has claimed King Charles "sounded giddily elated – like a lottery winner" during a phone call immediately after Princess Diana's death.
The 9th Earl Spencer, 62, wrote the shock allegation in his memoir, Swan Song: Diana, My Sister, in which he seeks to correct "untruths" about his sister and the monarch's ex-wife, who died aged 36 after being fatally injured in a car crash in the Pont de l'Alma tunnel on August 31, 1997.
