Dear Mr Jenkins

Welcome from your annual leave and your assistance advice in the past prosecution cases and I
understand you are assisting my colleagues at present. I need your urgent assist judge has this
morning ordered the prosecution to have the following report ready to be served within Seven
days.

On advise Post Office Limited have appointed one of their investigators, Helen Rose as disclosure
officer dealing with Horizon challenges. She has prepared a document/ spread sheet detailing all
such cases, past and present, approximately 20 in total, although none thus far successfully argued
in court. Post Office limited have been advised to obtain, an experts report from Fujitsu UK, the
FUJ00226331
FUJ00226331

Horizon system developers, confirming the system is robust. Post Office Limited maintain the
system is robust, but in light of adverse publicity, from legal viewpoint is that defence should be
given opportunity to test the system, should they still wish to do so, on consideration of our
report.

You will need to consider the Disclosure officers document/ spread sheet(see attachments) and
need to address in your report the following issues:

1) A description of the horizon system (In laymen’s' terms so that a jury can understand what it is
and what it does)

2) A declaration that it has yet to be attacked successfully.

3) A summary of the basic attacks made on the system concentrating on any expert reports served
in past cases. If there are none then state that no expert has yet been found by any defence team
civil or criminal to attack the system. (at the moment there seems to be little more than griping by
defendants that the system must be at fault without saying how)

4) Plainly, like all accounting systems, there is room for human error (Keying in wrong amounts
etc) are you able to state that innocent human error is unlikely to produce the types of
discrepancies of many thousands of pounds over many months.

If you require any further information or wish to discuss please do not hesitate to contact me.
Regards

Jarnail Singh
