I'm with @MrsFinkelstein. I'm very interested in royal history, but was always mildly republican/disinterested in the current crop of royals. The more I listen to republicans and their depressing bellyaching bordering on sheer nastiness, and their lack of a clear alternative vision, the more I'm in favour of the status quo of constitutional monarchy, even with all its faults and the less than perfect humans at the centre of it.
Anyway, I hope hope this is a temporary blip for Charles and he'll be back on form soon. I think he's done a very decent job so far - after a lifetime of public service, charity work through the Prince's Trust and other charitable endeavours, and his innovative vision and campaigning in the fields of organic farming and environmental stewardship. And I really like Camilla too, with her work with DV charities and reading. They had enormous shoes to fill, and I think they have done so with quiet dignity, humour and just being themselves.
