ITV commissions People Vs Post Office: The Real Story
The film will be an accompaniment to the four-part drama coming to ITV next year and will give exclusive access to campaigner Alan Bates.
Bates has rigorously campaigned for nearly 20 years to uncover and expose the scandal that has been described as the most widespread miscarriage of justice in the British legal history.
Over 14 years, the Post Office accused hundreds of sub postmasters of theft, over 700 were given criminal convictions and many went to prison, ruining livelihoods and destroying reputations.
