Queen Elizabeth II's 97-year-old husband Prince Philip emerged unscathed after being involved in a road traffic accident near the monarch's Sandringham Estate on Thursday, Buckingham Palace said in a statement.
"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.
Eyewitnesses said the duke was driving a Range Rover out of a driveway when his vehicle was involved in collision with another car. He was unhurt but 'very shocked'.
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."
