Dawn Beech and Lady Brittan give their accounts in new documentary The Unbelievable Story of Carl Beech

Beech made headlines in 2014 with shocking allegations of abuse by an elite VIP pedophile ring, which he claimed included former home secretary Lord Brittan and former Prime Minister Edward Heath, among many other powerful figures.

Ultimately, his accusations were found to be false, resulting in an eventual 18-year prison sentence for perverting the course of justice, fraud and child sex offences.

A new documentary, The Unbelievable Story of Carl Beech, talks about the devastating consequences of his terrible lies, with interviewees including his ex-wife Dawn Beech and Lady Brittan.

Lady Brittan, whose accused husband passed away before his name could be cleared, has spoken in the programme about that dark chapter in her life.

"I cannot fathom why anyone would do that to a group of random people," she tells this week's Radio Times. "It’s beyond my comprehension.”

Lady Brittan continues: “I was traumatised with shock. Like a fly stuck to a flypaper, I couldn’t move.

"l wish it had never happened. Life would have been very different if it had never happened. I think if I’d not had a very good set of friends and supporters, you wonder whether you wouldn’t have had a nervous breakdown."

Beech’s family has also suffered as a result of his crimes, as ex-wife Dawn delves into during the documentary.

"I think Carl has got to realise what he’s put me through, what he’s put his mother through and what he’s put our son through," she said. "It’s his mum and his son that are really the people who have been seriously damaged by this.”
