Lee Castleton, one of the prime movers in the fight back over Horizon, wrote to Kenneth Clarke MP on the subject of Horizon, and the following is the acknowledgement he received from an assistant:
"I know that Mr Clarke will be grateful to you for writing to him with your thoughts on the Horizon accounts system, and I would also like to make sure that Jonathan Djanogly MP, the shadow minister for the Post Office, is also aware of the serious nature of your concerns."

It might be an idea for anyone out there with concerns on this subject to also write to Jonathan Djanogly.
