Prince William paid tribute to his 'extraordinary' grandfather Prince Philip, saying his life was 'defined by service'

• Prince William paid tribute to his grandfather Prince Philip after the 99-year-old's death.
• He said Philip was an "extraordinary man" whose life was "defined by service."
• He said he and his wife, Kate Middleton, would continue to support the Queen in the years ahead.

Prince William says his grandfather Prince Philip was an "extraordinary man" whose life was "defined by service" in a tribute written following the 99-year-old's death.

William's statement was published on the Royal Family's website on Monday.

"I feel lucky to have not just had his example to guide me, but his enduring presence well into my own adult life - both through good times and the hardest days," he wrote. "I will always be grateful that my wife had so many years to get to know my grandfather and for the kindness he showed her. I will never take for granted the special memories my children will always have of their great-grandpa coming to collect them in his carriage and seeing for themselves his infectious sense of adventure as well as his mischievous sense of humour!"

William added that he and his wife, Kate Middleton, would continue to support the Queen in the years ahead.

"I will miss my Grandpa, but I know he would want us to get on with the job," he wrote.

Prince Philip "passed away peacefully" at Windsor Castle on Friday, Buckingham Palace said last week.

William and Kate's charity, the Royal Foundation, also displayed a photo of Prince Philip on its website to pay tribute to the Duke of Edinburgh.
