Today, royal fans across the world would have been celebrating a very big milestone - a rare day to come by on any royal calendar.
Today would have been Prince Philip's 100th birthday, his big centenary - something that royal staffers had been planning celebrations for right up until his passing in April.

Last week, the 95-year-old Monarch was presented with a special Duke of Edinburgh Rose - this was given to mark what would have been his 100th birthday.
