Princes William and Harry will mark the 10th anniversary of their mother's death today.

The brothers will mark a decade since Diana, Princess of Wales, was killed in a car crash, by holding a special memorial service at the Guards' Chapel in London.

Diana spent her early years at Park House, a carrstone country retreat on the Royal Estate at Sandringham. She was born in the house on July 1, 1961, the youngest daughter of Johnnie and Frances Spencer - the late Earl Spencer and the late Hon Mrs Shand-Kydd.

Ahead of the poignant milestone, members of the public left floral tributes and messages at Kensington Palace, the focus of the outpouring of grief in the wake of August 31, 1997.

The Duchess of Cornwall will stay away from the thanksgiving service after criticism that it was inappropriate for her to attend.

William and Harry invited their stepmother, but the decision caused controversy, with some adamant it was not right for the woman who had an affair with Charles while he was still married to the princess to be there.

The princes will join other members of the royal family and the Spencers at the chapel at Wellington Barracks for the church service.

They have overseen all the arrangements, including the music and hymns, helped by Diana's family.

The Queen, the Duke of Edinburgh, Prince Charles and more than 30 other members of the royal family will gather along with Diana's siblings Earl Spencer, Lady Sarah McCorquodale and Lady Jane Fellowes.

Sir Elton John, Sir Cliff Richard, Lord Attenborough and celebrity photographer Mario Testino - all friends of the late princess - were invited by the princes.

Prime minister Gordon Brown and former PMs Tony Blair and Sir John Major will also be among the 500 guests.

A sculpture commemorating the anniversary of the princess's death was unveiled on Thursday at Kensington Palace Gardens.

The 10 golden dandelions were individually gold-leafed by members of the public visiting the gardens over the summer.

The work was designed by the artist Sofie Layton and inspired by dandelion seed clocks, said to be a reminder of much missed loved ones, and by the sea of flowers left at Diana's former home in the aftermath of her death.
