More than 45 individuals being investigated in relation to widespread miscarriage of justice

The police criminal inquiry into the Post Office Horizon IT scandal is investigating more than 45 individuals, with seven formally identified as main suspects.

The investigation, which the police described as unprecedented in size and scale, is the first to examine potential offences of perjury and perverting the course of justice by those who made “key decisions” on Post Office investigations and supporting prosecutions of branch-owner operators.

The police would not reveal the names of the seven suspects, but four of them have been interviewed. The number of formal suspects is expected to rise.

More than 900 post office operators were prosecuted by the Post Office between 1999 and 2015 because of faulty Horizon accounting software that made it look as though they had been committing fraud.
