The Conservatives have announced that adults over 21 who murder children under 16 will never be released from custody. It has made for a good Sun newspaper op-ed; justice secretary Robert Buckland is pushing against an open door with the electorate.

In prison, where hierarchies exist as much as in the free world, child killers and paedophiles are at the bottom of the pile. Many are targeted for retribution. Only last month, Richard Huckle who sexually abused up to 200 Malaysian babies and children was found dead in his high-security prison cell.
