ITV’s Mr Bates v The Post Office is simply superb. As is ITV’s accompanying documentary. Harrowing and heartbreaking when you learn the appalling, unjust ordeals so many sub-postmasters — the very epitome of the decent backbone of Britain — had to go through. Watch it and you will be simultaneously angry and tearful. But even more astounding is the callous malevolence of the Post Office — and even more shaming is the fact that none of its appalling executives has ever been held to proper account.
