US executioner calls for end to death penalty

A man who was in charge of executions in Georgia has begun campaigning against the death penalty to ease his "tremendous guilt."

Allen Ault oversaw deaths via the electric chair in the 1990s and even staged execution rehearsals to make sure the procedure went correctly.

Speaking to BBC Radio 5 live's Victoria Derbyshire, he claimed his campaign to prevent further executions was a way of finding "forgiveness."

Mr Ault said, "When you realise... that you just murdered another human being and you were the one that gave the order - you feel totally responsible."
