I feel so sceptical about that really. So the firm that calls in the crisis management team appoint their person as your spokesperson. There is no independence there.
That would be like you getting a divorce and your spouse appointing her friend as your solicitor.
He wasn't acting for the McCanns when he told them that the twins could no longer use the creche. Kate was so upset for them;
"Poor Amelie and Sean. They were the ones who would suffer. We’d tried so hard to provide them with stability, to make sure they had other children to play with and lots of activity, and now even this was to be taken away from them" [madeleine Kare McCann]
I can't help but comment on that passage. As I understand it Mark Warner had been allowing the twins to attend the creche ever since Madeleine's disappearance three months earlier. I see nothing in Kate's book suggesting that she and her husband had needed to put any effort into persuading them to do that.
