The victims of what’s been described as the worst miscarriage of justice in Britain are still waiting for compensation.
In 1999, Britain’s Post Office embraced its new digital future, by introducing a computer system called Horizon.
This platform would soon be used by thousands of sub-postmasters and post mistresses across the UK, to provide essential services to communities.
Many realised this system was full of flaws – it looked as if the large sums of money were missing.
It often registered financial losses, leading to more than 700 employees of the Post Office being prosecuted for theft and false accounting.
Many were sent to jail and lost their livelihoods.
