The Duke and Duchess of Cambridge and Prince Harry are to attend a service to rededicate the grave of Diana, Princess of Wales, almost 20 years after her death.

The private service is at Althorp House in Northamptonshire on Saturday, which would have been her 56th birthday.

Prince George, Princess Charlotte, Princess Diana's brother, Earl Spencer, and her two sisters will also be there.

Prince Charles and the Duchess of Cornwall will be in Canada.

The service will be conducted by the Archbishop of Canterbury Justin Welby.

The Princess of Wales died on 31 August 1997 in a car crash in Paris, when the Duke of Cambridge was 15 and his brother was 12.
