Question to the Department for Business and Trade:

To ask His Majesty's Government how many formal complaints from Post Office sub-postmasters about the Horizon software that was updated in 2017 (1) have been made, and (2) still need to be resolved, about discrepancies and cash shortfalls in individual post offices; and in what towns and cities these complaints were made.

This is an operational matter for Post Office Limited. Post Office however continues to make improvements to the system and will be moving away from Horizon to a new cloud-based IT system. Government recently announced that it is providing £103 million to help with the development of the replacement for the Horizon IT system and to ensure Horizon is maintained while that replacement is rolled out.
