So?
The question was “isn’t the post office part of Royal Mail”?
No, I asked that question after being told, wrongly, that the postmasters involved in the scandal wouldn't be taking on the might of the Royal Mail. For the vast majority they would have as they were still part of Royal Mail then. I admit I thought they were all still one and the same now that's why I asked the question. It's a moot point. My post mentioned how hard it is for the little person to take on a huge corporation, be it the Post office or Royal mail.
