Post Office prosecutors tasked with investigating sub-postmasters in the notorious Horizon scandal used a racial slur to classify black workers, according to documents obtained by campaigners.
Fraud investigators were asked to group suspects based on racial features and used a racist term for staff from the colonial era of the 1800s which refers to people of African descent.
The Post Office Horizon scandal, which has been described as “the most widespread miscarriage of justice in UK history”, saw hundreds of innocent postmasters convicted.
