The Memorial Service for Princess Diana, held this morning at the Guards’ Chapel, Wellington Barracks in London, set the tone for reconciliation that her sons so clearly want.

Invitations to the two Camillas, the Duchess of Cornwall — who pulled out earlier this week — and Mohamed al Fayed’s daughter, spoke volumes about their wish to draw a line under the enmities that have arisen since Diana’s death ten years ago.

Prince Harry gave a moving address in his own words which totally concentrated on her role as a mother.

By contrast, the Bishop of London’s sermon seemed bullish and a little out of step with the mood in the Chapel, although it too called for a healing of old wounds.

Small crowds turned up to watch. They gave the Queen and Prince Philip a loud cheer, but Prince Charles arrived to a stony silence.

It was a splendid occasion which will be much appreciated by Diana’s supporters worldwide.

Prince William has invited Camilla al Fayed (pictured), daughter of Mohamed and half-sister to Dodi, to attend the service for Princess Diana on August 31st.

William hopes it will be a gesture of reconciliation to the Al Fayed family, who lost a son in the Paris car accident ten years ago.

A Royal source said, “They [the Princes] lost a mother in very tragic circumstances but Camilla also lost a much-loved brother. Obviously it would have been impossible to invite Mohamed but they thought it appropriate that someone from his family was invited and, as they have met Camilla in the past, the invitation was extended to her.

“They are delighted that she has accepted. I wouldn’t go so far as to say that the past is gone and forgotten but William and Harry want to acknowledge their shared grief.”

From the picture, though, it’s easy to see why she was invited.

The Queen and Prince Philip will attend the service, together with the Prince of Wales, the Duchess of Cornwall and members of Diana’s family.
