Justice for Postmasters

A total of 39, Sub Postmasters have had their criminal convictions overturned by the courts, no doubt with more to follow.
It is now generally accepted, that there is a prima facie case for prosecuting several past and present top Post Office individuals, as there appears to be clear evidence that vital evidence was withheld from the courts, which resulted in findings of guilt, whereas with knowledge of the full facts, such guilty verdicts would have not been made.
Many lives have been ruined due to the withholding of such evidence.
Police Investigations must follow re attempting to pervert, or/and actually perverting the course of justice.
Please support this petition, to get justice for those so badly treated, in what is now regarded as the worse case of 'misscariage of justice in the UK.
