Prince Harry has joined the Queen and other members of the Royal Family at a service in Windsor Castle to commemorate the Queen Mother and her daughter Princess Margaret.
It is 10 years since the Queen Mother died peacefully in her sleep aged 101, seven weeks after Princess Margaret passed away at the age of 71.
Both deaths caused a large outpouring of public grief.
Also present at the service was the Prince of Wales, the Duchess of Cornwall and the Duke of York.
The service was held inside St George’s Chapel in the grounds of Windsor Castle and was led by the Dean of Windsor.
He said: "Each of us here this morning will cherish some special personal memories; memories that awaken once again sentiments of affection and respect.”
There were some notable absences with the Duke and Duchess of Cambridge reportedly unable to attend as they were on a skiing holiday.
