Question to the Department for Business and Trade:

To ask His Majesty's Government whether the Post Office Horizon software system that was updated in 2017 has any issues with discrepancies of cash shortfalls in individual Post Offices; and if so, in how many Post Offices such problems have occurred.

There have been several versions of Horizon since its introduction in 1999 and the current version of the system, introduced from 2017, was found in the Group Litigation to be robust, relative to comparable systems. Post Office continue to make improvements to the system and will be moving away from Horizon to a new IT system. The Government is providing funding to support this programme.
