"The Queen has voluntarily paid income and capital gains tax since 1992"

Yes well just two questions from me. First, did she pay the back tax for the forty years she was Queen before 1992? Second, can I make MY tax payments voluntary too?

The question of their being a tourist draw is in the realms of received wisdom. It can't be proven and never will be. What is clear is that not a single royal location was in the top twenty UK tourist attractions, last time I looked.
