Britain Queen's feisty husband Prince Philip turns 90

Britain's Prince Philip, the feisty husband of Queen Elizabeth, has turned 90 on Friday. The son of the exiled Prince Andrew of Greece, is the longest-serving consort and oldest-serving spouse of any British monarch.

Known for his blunt talk and verbal gaffes, Philip married the queen in 1947. But, despite being a near stable companion at the queen's side during her long reign, the prince hasn't sought the limelight himself.

According to sources, Philip will be spending the day as he has much of life performing official duties in his role as Queen Elizabeth's husband, said a Reuters report.

It's a normal working day for him. There's no celebration as such, his spokeswoman said. However, he will hold a reception to mark the anniversary of a charity for the deaf and in the evening he will chair a conference for senior British military figures followed by a dinner, sources said.

The only formal event to mark his birthday will take place on Sunday with a special service at St George's Chapel in Windsor Castle. The Windsor Castle is one of the queen's residences, west of London. The event will be attended by most of the royal family.
