John Edwards, 61, from the charity Walking Free was buried in an eight-foot box in Halifax to raise awareness of the difficulties faced by those with addiction and suicidal thoughts. He used his time underground to take calls and answer emails and texts from those who wanted to talk about their problems. Mr Edwards spoke to Premier from the grave and said: ‘It’s been suicidal people, gangsters, drug addicts, their mothers and fathers phoning in.

‘We’re bringing words of life from the grave to these people.’ Mr Edwards has founded rehabilitation centres, overcome Hepatitis C from dirty needles and spent time in mental health institutes. The former addict says he has been clean and sober for 25 years after God turned his life around.
