Buckingham Palace has played down fears about the Duke of Edinburgh's health after he was pictured with a badly bruised eye.
The Duke, 91, was photographed in Canada with the mark below his right eye during his first major foreign trip since his time in hospital with a bladder infection last August.
It is understood that he did not fall and simply woke up with the bruising a few days ago.
A palace spokeswoman said: "He is well and is currently undertaking an engagement in Canada."
It is not the first time Philip has suffered a black eye.
In 2004, he was pictured with the injury when he arrived with the Queen to open a new power plant near Port Talbot in south Wales. The Duke had slipped in the bath and caught his eye with his thumb.
Meanwhile, the Queen was spotted with an extremely bloodshot eye at a polo match in Surrey last year.
