Terms used to categorise branch operators in Horizon IT scandal by race said to be common in 1980s public sector

Language in an infamous Post Office document that categorised branch operators as “negroid types” was common in the public sector from the 1980s but continued to be used in the scandal-hit organisation until 2016, an inquiry has heard.

The document, which revealed that lawyers investigating post office operators in the Horizon computer scandal used a racist term to categorise black workers, first became public in May last year when it was released to campaigners seeking justice for those wrongfully prosecuted.
