I think that the king has done the right thing, Andrew is no longer a senior royal, so the taxpayer shouldn’t pay for his personal security. If his brother is willing to pay for his security, that’s an issue for them to sort out between them - I’m not interested.
I am a Republican, and loathe PA. But I think if you have a royal family the individuals within it need security, however unpleasant those individuals may be. It's another argument not to have a monarchy.
Anyone ,regardless of their lifestyle/ misdemeanours should have protection if their life is threatened. I abhor PA if he is guilty but think he is entitled to the same safety considerations as the rest of us.
