The Queen's cousin, the Duke of Kent, left hospital on Tuesday afternoon after being successfully treated for a dislocated hip. It is understood that Prince Edward, 79, sustained an injury while staying at the Balmoral estate in Scotland and was taken to Aberdeen Royal Infirmary on Sunday.
A palace spokesman said at the time: "I can confirm that the Duke of Kent was admitted to Aberdeen Royal Infirmary in Scotland for treatment of a hip injury."

The Duke undertakes a large number of royal engagements on behalf of the Queen. He is well known for his role as president of the All England Lawn Tennis Club, and for presenting trophies to Wimbledon champions.
He is the son of Prince George, the younger brother of King George VI and King Edward VIII. He became the Duke of Kent at the age of six when his father died in a wartime flying accident in 1942.
At the time of his birth, Prince Edward was seventh in the line of succession to the throne of his grandfather King George V.

When the 7th Earl of Harewood died in 2011, the Duke became the Queen's eldest living paternal cousin, although he is nine years younger than the Queen herself.
The Duke resides at Wren House, Kensington Palace, along with his wife the Duchess of Kent, whom he married in 1961. The couple have three children together, George, Earl of St Andrews, Lady Helen Taylor and Lord Nicholas Windsor. None of them carry out royal duties.
Edward's wife prefers to be known as Katherine, Duchess of Kent, despite the title being the style of a divorced or widowed peeress.
