Duke Out Of Hospital
The Queen's cousin the Duke of Kent was taken to hospital after suffering a hip injury, Buckingham Palace has said.
It is understood the Duke, 79, sustained a suspected dislocated hip while staying at the Balmoral estate in Scotland.
He was taken to hospital on Sunday and released at lunchtime on Tuesday.
A palace spokesman said: "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 and as president of the All England Lawn Tennis Club he has presented trophies to Wimbledon champions.
He suffered a "mild'' stroke in 2013.
The Duke is the son of Prince George, the younger brother of King George VI and King Edward VIII. He became the Duke of Kent at just six when his father died in a wartime flying accident in 1942.
