A reformed gangster turned preacher, who's held workshops for prisoners around the globe, has spoken of his shock after Lewes Prison banned his books.
John Lawson's given talks in some of the world's most dangerous prisons in the hope of transforming people's lives. Yet, when his books were requested by Lewes Prison's chaplain, they were rejected on the grounds of security.
With prison libraries containing books on the Krays, among others, John says he fears he's being discriminated against - either as a former prisoner or a Christian. Andy Dickenson reports.
