The Civil List has n't been cancelled, just cut back. For 2001 the figure is £37 million.
Theroyal Family doesn't get that money for themselves, however, it provides for the upkeep of royal palaces and art treasures, diplomatic visits abroad, hosting visting heads of state, offical functions in the uk etc.
The truth is, get rid of the monarchy and the bill wouldn't go down at all. The palaces are national treasures and have to be maintained like any historic monuments, the government would have to pay a lot to drum up the sort of business a foreign visit by a royal generates for the country, visiting heads of state would still have to be entertained etc.
Keeping the royal family probably doesn't cost anything, even when you don't count the amount of tourism revenue they generate.
