QUEEN Camilla speaks for the first time about whacking a man in the goolies – after he tried to grope her on a train.

Camilla, 78, fought back after the pervert sat down next to her on a train to Paddington when she was a teenager in the 1960s.

Speaking on a special Radio 4 Today programme, the Queen opened up about the incident for the first time.

The Queen was talking to John and his daughter Amy Hunt during a radio special with Theresa May and Emma Barnett.

Camilla recalled having been on her way to meet her mother when “this boy – man – attacked me” adding “I did fight back”.

The Queen said: “I remember something that had been lurking in the back of my brain for a very long time.

“That, when I was a teenager, I was attacked on a train… I remember at the time being so angry.”

The Queen recalled 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?’ I had been attacked.”

Camilla said she had “sort of forgotten” what had happened to her, but that the courage of the Hunt family had prompted her to speak about her experience.

She added: “I was so furious about it and… when 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.”

After hearing the Queen’s story, Amy told her: “Thank you for sharing that, Your Majesty. It takes a lot to share these things because every woman has a story.”

BBC racing commentator John Hunt‘s wife and two daughters were murdered at their home in July last year.

Louise Hunt, 25, her sister Hannah Hunt, 28, and their mother Carol Hunt, 61, were killed by Louise’s ex-partner Kyle Clifford at their home in Bushey, Hertfordshire.

At Cambridge Crown Court in March, Clifford, 27, was sentenced to a whole life order, after pleading guilty to the murders and his conviction for raping Louise.

“It remains really difficult on a minute-by-minute basis,” Mr Hunt told the BBC.

“You have to try and find the strength in our position to arm yourself with as many tools as possible that are going to help you get through that next hour.”

The announcement of the special broadcast coincides with the final day of the UN’s 16 days of activism against gender-based violence.

It is understood that Camilla opened about her experience to explain how women suffering groping or sexual assaults can lead to wider issues.

And her recollection is not trying to compare her incident from the 1960s with what the Hunt family went through.

The incident, in which Camilla whacked her groper in the goolies with her shoe, was first reported in Valentine Low’s sensational book ‘Power and the Palace: The Inside Story of the Monarchy and 10 Downing Street’, in September.

In a conversation with Boris Johnson in 2008, she reportedly told him: “I did what my mother taught me to.

“I took off my shoe and whacked him in the nuts with the heel.”

She then reported the incident to cops at Paddington Station and the man was arrested, it was reported.

Camilla has fought tirelessly for victims of sexual and domestic violence in her adult life and Royal role.

She regularly holds engagements at Sexual Assault Referral Centres (SARCs) meeting staff and victims in the UK.

A hit ITV documentary ‘Her Majesty The Queen: Behind Closed Doors’ aired last year

It is understood The Queen has not wanted to talk about the train incident in the past as she has not wanted to distract from the victims of sexual violence.
