Unfortunately since Prince Charles is no longer doing anything "news worthy" they had to find another scapegoat.
Ann couldn't give a toss and in her own succinct way, memorably told them to "Naff Off" back in her Eventing days. It looks like it either stuck or they're just plain scared of her because they leave her alone for the most part.
Once Edward and Sophie cut all their private employment they too are good hardworking royals and have nothing "newsworthy" to report. Perhaps they are scared of the Queen!
That leaves Andrew, a bachelor, and we all know that when he was a lad he was "a bit of a lad". So we have a divorced man who absolutely must be doing something wrong . . . . something, anything, there has to be dirt to be found. If not, we invent it.
I think Andrew is the victim of a decade or more long bash. He can't officially reply, yet most of the people he has mixed with in the course of his government sanctioned appointment were introduced to him by members of trade and industry, some even from the government itself. Yet, when their bad habits are exposed it is Andrew who is at fault for becoming a friend. Where is the culpability for those who sent him off to make deals and money for the country.
As to Andrew flying first class and staying in first class hotels, well really, that's why they sent him. A Prince of the Realm is expected to travel and entertain on the same level as any CEO, that's part of the cachet of having a Prince glad handing for you. Are any of those movers and shakers to be found at the economy gate in an airport or and no star hotel? I think not!
It's time people realised that Andrew's use to trade and industry lies in his being and acting like a Prince and not your average Joe. A Prince has the entrée into a world that average people and even many CEO's don't!
