Some of those emotions, he says, are the result of generational trauma.

He says the men may be fathers who grew up without a dad themselves, or who witnessed or experienced domestic violence as a child, or had a father struggling with mental health issues, alcohol or drug addictions.

Mr Brown says: “They’re angry about not having had a dad there, or they’re worrying they’re going to repeat what their dad did, and holding all that anxiety and anger towards their dads, which then plays out.”

He says he was inspired to set up the group after rebuilding a difficult relationship with his own father, which in turn helped him recognise the difficult relationship he had had with his sons – now adults – and to apologise to them.

“There’s always hope,” he tells me. “We have to give hope. It’s about the children and young people. We are not here to judge. We need to understand how they got there, and put a solution in place.”
