The brother of Diana, Princess of Wales, has said he still has nightmares about the "harrowing" experience of her funeral.
Earl Spencer, whose family home is at Althorp in Northamptonshire, walked along Princes William and Harry as part of the funeral procession in 1997.
Speaking to BBC Radio 4's Today programme, he said it must have been a "million times worse" for his nephews, who were just 15 and 12 at the time.
Princess Diana was killed in a car crash in Paris on August 31 1997.
A huge outpouring of grief followed her death, which shocked the world.
