He’s specifically suing to say that the Mirror Group used illegal means in obtaining the information that they published though. Not that it’s shit having stories written about him.There is very wide latitude in witness statements for civil cases. He is free to mention the appalling Mr. Morgan, he is free to mention death (his mother's, I assume) and the Mirror's barrister is free to question him on it. Perhaps you are forgetting that he doesn't actually need to 'prove' anything. All he needs to do is establish that on the balance of probability the Mirror was using illegal means to acquire information. As the Mirror has already admitted doing it at least once they don't really have much of a leg to stand on.
Having been on the receiving end of being dorrstepped by the Mail when trying to take my small daughter to nursery complete with camera flashes, shouting etc., and then having the horrible experience of a completely distorted and untrue article written about a friend and myself in the Mail on Sunday I can say, hand on heart that it felt utterly violating. The idea of going through most of your life feeling that way makes me want to throw up. The media in this country is an absolute disgrace and it's time there was a crackdown. I hope Harry and the others in this case win, and win big.
This will be thrown out and he’ll have to pay the legal costs of the papers, and they’ll rightly rinse him for being thick enough to accuse them of phone hacking and blagging with zero evidence.
