Charles has taken over many of her duties. Do you think he did it in her name?
I think the Queen was between a rock and a hard place. She probably saw that if diplomatic immunity was not revoked for Andrew, the whole question of diplomatic immunity for the Royal Family would be called into question. She also realised that revoking it was, largely, gestural because the case in the US is civil and there is currently no danger of extradition. If Andrew stays in the UK then he has a sort of de facto immunity.
What I think is going to be interesting is that disclosure is going to happen now. So Ms Giuffre's lawyers are going to be demanding documents from Andrew. They've already been told that there is no medical documentation about his inability to sweat and no corroborating evidence for the supposed trip to Pizza Express.
Ms Giuffre's lawyers will have a field day in court with both of these - and both of these are fairly big lynch-pins in Andrew's case. An alibi is not an alibi unless you have proof. Similarly, his claim that he couldn't sweat, so her story must be untrue falls apart. Which then leads to the question of why he hasn't rebutted her story in any other way ? Why rely on something that is so flimsy ? The obvious answer is that he has nothing else to rely on, but I'd be willing to entertain other ideas...
You can see why things are looking really shaky for him now and also, I think, it's obvious why he's trying to get the case thrown out on technicalities. It's because he hasn't got anything else...
