doobydoo patronising much?
As I've already said on this thread, I'm no monarchist, and given a vote tomorrow, I'd vote for a republic. And fwiw, I think the duke is a bit of a national embarrassment. I couldn't care less thst they have no knowledge of/interest in me. 
But I also have some compassion, I'm able to separate the individuals from the institution and frankly, I would feel sorry for any elderly man who fell ill during an important family occasion. I just think it's a bit low to start making political capital out of a 91 year old bloke who may well be on his very last legs.
