It’s hard to overstate the extent of the miscarriage of justice caused by the Post Office Horizon scandal.
Between 2000 and 2014, more than 700 branch managers across the UK were given criminal convictions because a faulty computer system made it appear as if money was missing.
The lives and reputations of wholly innocent people were ruined. Some of the postmasters went to prison and some died before they had a chance to clear their names.
