Queen Camilla has spoken for the first time about how she fought off a sex attacker on a train when she was just a teenager. 

The King's wife chose to address the issue publicly with BBC racing commentator John Hunt, whose wife and two daughters were brutally murdered last year, as part of a wider conversation about women, violence and misogyny on Radio 4's Today programme this morning.

The Queen said she was left 'so angry' and 'furious' after the attack which took place during a journey to meet her mother. 

She explained that while she had 'sort of forgotten' about her ordeal, she was encouraged to speak up after hearing about the courage of Mr Hunt and his eldest daughter Amy.   

'I remember something that had been lurking in the back of my brain for a very long time,' the Queen said. 'That, when I was a teenager, I was attacked on a train… I remember at the time being so angry.'

Camilla explained during the panel discussion, that was guest edited by former Prime Minister Baroness Teresa May, how she 'fought back' against the sex pest. 

She said: 'Somebody I didn't know. I was reading my book, and you know, this boy, man, attacked me, and I did fight back.

'And I remember getting off the train and my mother looking at me and saying, "Why is your hair standing on end", and "Why is the button missing from your coat".

'But I remember anger, and I was so furious about it, and it's sort of lurked for many years.

'And I think, you know, when all the subject about domestic abuse came up, and suddenly you hear a story like John and Amy's, it's something that I feel very strongly about.'

The Queen has campaigned for more than a decade on the issue of sexual violence against women and domestic abuse, making it a cornerstone of her public work. 

This morning she praised the courage of the Hunt family, saying: 'I'd just like to say, wherever your family is now, they'd be so proud of you both.

'And they must be from above smiling down on you and thinking, my goodness me, what a wonderful, wonderful father, husband, sister.

'They'd just be so proud of you both.'

And after hearing Camilla's story, Amy Hunt told her: 'Thank you for sharing that, Your Majesty. It takes a lot to share these things because every woman has a story.'

The Queen's sex attack ordeal was first reported earlier this year in a book titled Power and the Palace by journalist Valentine Low.
