A memorial service marking the death of the Princess of Wales 10 years ago in Paris is to be held in central London, it has been announced.
Princess Diana died in a car crash
The service, which is being organised by her sons Princes William and Harry, will be held at the Guards' Chapel, Wellington Barracks, on 31 August.
About 500 people will attend the "personal and... family occasion", Clarence House said.
Tickets will not be sold to the public but the event will be televised.
The Princes will be joined at the service by the Queen, the Duke of Edinburgh, Prince Charles and their stepmother, the Duchess of Cornwall.
Diana's brother, Earl Spencer, will also be among the congregation, as will her sisters Lady Sarah McCorquodale and Lady Jane Fellowe.
The guest list, which is to be drawn up by the Princes and the Spencer family, will include Diana's friends and representatives from the charities she supported.
A Clarence House spokesman said: "Members of the public will be represented in the charities and organisations, which will make up about 100 people."
The BBC is to broadcast the event live.
Padre Patrick Irwin, Chaplain to the Household Division, will lead the service and an address will be delivered by the Dean of the Chapels Royal, Dr Richard Chartres.
