Post Office failed to train Horizon investigators properly, says criminal expert

Policies did not ensure fair trial of postmasters accused of wrongdoing, says inquiry's prosecution lead

The Post Office did not provide adequate guidance and training to prosecutors who investigated branch operators accused of wrongdoing in the Horizon IT scandal, according to a criminal prosecutions expert.

More than 700 post office operators were prosecuted in England and Wales between 1999 and 2015 for theft, fraud and false accounting because of faulty accounting software installed in the late 1990s.
