Prince Philip unhurt in traffic accident

"The Duke of Edinburgh was involved in a road traffic accident with another vehicle this afternoon," said a spokesman.

"The Duke was not injured. The accident took place close to the Sandringham Estate. Local police attended the scene," it added.

The couple spend most of the winter at the residence in Norfolk, south east England, which continues to operate as a sporting estate.

Philip, known for his forthright manner and off-colour jokes, formally retired from public life in 2017.

Born a prince of Greece and Denmark, he married then princess Elizabeth on November 20, 1947 at Westminster Abbey in London.

On their golden wedding anniversary in 1997, she said of him: "He has, quite simply, been my strength and stay all these years."
