When the words "feminism" and "royalty" are mentioned, there is one former Hollywood actress who immediately springs to mind.
But royal experts recently revealed which member of "The Firm" is the greatest feminist - and the answer will come as something of a surprise.
Speaking during a panel discussion on Yahoo's The Royal Box, The Sunday Times royal correspondent Roya Nikkah gave her take on the issue and sensationally declared Prince Philip is the Windsor's resident feminist.
As reported by Express.co.uk, Ms Nikkah said: "A man who in the early 1950s, who was soaring up to the top of the navy and would have gone all the way to the top had he not given up his career..who wasn't even able to give his own surname to is children, who has literally stood behind his wife for pushing 70 years.
"A man who has supported his wife...to a very successful reign - if that's not being a feminist role model, I don't know what is."

The journalist praised the Duke of Edinburgh for acting as the "bedrock" to Queen Elizabeth and their family, and lauded him for playing second fiddle to "probably the most famous woman in the world" for seven decades.
Prince Philip, now 97, has certainly devoted the best part of his lifetime to royal servitude.
At the celebration of their Golden Wedding Anniversary in 1997, Her Majesty the Queen described her husband as her pillar saying: "He has, quite simply, been my strength and stay all these years."
Their marriage is the longest union of any British sovereign in history.
