I understand the need for diplomatic niceties to be observed. That's why when a royal head of state dies, I'm perfectly happy for one of our royals to attend the funeral. But why on earth do we have to send the prime minister as well? ... Wouldn't it be nice if, like Germany, we could halt our arms sales to what is undoubtedly one of the nastiest regimes on the planet. And when the new king dies - he's already 79 - perhaps we could send Prince Charles on his own. I'm sure he'd manage just fine.
