I had intended to keep this a Royal Wedding-free zone, but could not resist reproducing this article from THE COMMONWEAL, Vol. 1, No. 7, August 1886. (Bear in mind that the sums quoted are from the late 19th. century, but the principle of the Royal Family being a drain on the public purse has hardly changed!!)
The Commonweal was the journal of the Socialist League, and was edited by William Morris, who was also one of its major contributors. I came across this in the course of my research for a paper I'm about to give on Morris.
