Baroness May brought together the Hunt family and Queen Camilla in her role of guest editor of the Today programme.

In 2015, while home secretary, Theresa May introduced the offence of coercive and controlling behaviour as part of the Serious Crime Act. During her time as prime minister, she set out plans for a Domestic Violence Bill, and – since leaving office – Baroness May has supported campaigns against sexual and domestic violence.

The former PM also spoke of her concerns about the influence of the online world.

“What people are able to see online is so important – because the law isn’t going to stop somebody who has just been so inculcated with that sense of anger and violence that they want to go out and do something like this,” she said.

“But we can try to stop that by… the education that they receive, showing them those positive male role models, so they are less influenced by the negatives they see.”

Queen Camilla is patron of the domestic abuse charity SafeLives, external and has worked alongside a number of other organisations, including Refuge.

“This is an epidemic that does not discriminate,” said Refuge’s chair Hettie Barkworth-Nanton.

“The more the Queen is prepared to share her own experience, not in a way that is ‘poor me’, but in a way that helps people recognise that so many are affected by this the better… she is helping give survivors a voice.”

Mr Hunt’s strong bond with his daughter, alongside their desire to create a powerful legacy out of what happened to their family, was evident throughout the Today interview.

“I think it’s really important to remember they had a sad death but they did not have a sad life… their life was full of so much love and joy and happiness and fun,” Ms Hunt said.

Mr Hunt told the Queen and Baroness May that his daughter’s strength had been a powerful comfort, despite them still working through things.

“I’m staggered that we are as well as we are. At the risk of embarrassing Amy, she’s been my best counsel from the word go. We talk all the time.

“I used to say ‘I couldn’t do it without you’, but now I say ‘I can do it with you’,” he said.

They have set up The Hunt Family Fund to support charities and projects that will inspire young women. It will work with initiatives around domestic violence and abuse but also get involved with subjects enjoyed by Carol, Louise and Hannah, including animal charities something Ms Hunt said was Louise’s “main passion in life”.

As the conversation wound up, the Queen told Mr Hunt and Ms Hunt: “I’d just like to say wherever your family is now, they’d be so proud of you both. Thank you.

“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.”
