> "In June 2016, Tim Parker, the Post Office's then-chairman, told government ministers he had stopped an investigation into Horizon on legal advice, because of the upcoming court action by postmasters. The existence of that letter from the former chairman was revealed by the BBC last month. In it, he said the Post Office would "instead address the issues through equivalent work taken forward in the litigation". Now, the discovery of the draft Bramble report indicates that the investigation into Horizon, originally ordered by the government, actually continued in secret for more than a year, focusing on the branches involved in the case. In it, Deloitte reviewed Horizon documents, examined transaction data and interviewed Fujitsu and Post Office staff. The purpose was to find out if Horizon was causing sub-postmasters' financial losses. Deloitte found that while remote tampering by Fujitsu was possible, it would be "a complex procedure" and "likely a 'programme' would have to be written and performed". In a table, the draft report detailed hundreds of debited transactions entered by "non-branch users", who the report explained "can access branches remotely for support purposes"."
