London — Prince William and Prince Harry will attend a private service at the late Princess Diana's grave on what would have been her 56th birthday.
In a brief statement, Kensington Palace said on Wednesday that the 1 July service will be conducted by the Archbishop of Canterbury and attended by Diana's family.
The Spencer family as well as Duchess Catherine, Prince George and Princess Charlotte will also attend.
The service comes several weeks before the 20th anniversary of her in August 1997 death in a Paris car crash.
Diana is buried on the grounds of Althorp estate, her family's ancestral home in the countryside near Northampton in central England.
William and Harry, who were 15 and 12 years old when their mother died, are marking the anniversary by commissioning a statue of Diana that will stand in the public gardens of Kensington Palace in London.
