There may be many reasons to argue against a monarchy but I don't think the cost is one of them."

Sandman, please read my first post. The costs are paid from the income from the Crown Estate which goes to the Treasury, so they don't add to the burden on the general taxpayer.

Do we need our head of state to do as much as the royal family does? Possibly not, but people seem to enjoy having royals open their hospital or visit their workplace, and it seems to generate tourist income as well.
