In a statement after the ruling at the Royal Courts of Justice in London, Post Office chairman Tim Parker said: “The Post Office is extremely sorry for the impact on the lives of these postmasters and their families that was caused by historical failures. “Post Office stopped prosecutions soon after its separation from Royal Mail a decade ago and has throughout this appeals process supported the overturning of the vast majority of convictions. “We are contacting other postmasters and Post Office workers with criminal convictions from past private Post Office prosecutions that may be affected, to assist them to appeal should they wish.
