"article here suggesting £500million just on visiting places linked to the monarchy"
Tower of London, hasn't been a full time Royal Residence since the 1500s, 2.4 million visitors.
Buckingham Palace, still a Royal Residence, 0,4 million visitors.
As said that suggests that kicking the Royals out of a building is a very beneficial thing to do, if it's tourists that you're after.
"So using that logic, Disney should get rid of Mickey yes?"
Hardly the same. Mickey can be kept going for minimal outlay by Disney. The tourist argument for the Royals accepts that they have considerable outlays but recoup those costs through tourism.
If Mickey cost a lot to put in the parks and no one was going there to see him we'd see Disney dump him pretty sharpish.
But that's presuming we should change our constitution to something that makes hard financial sense, and I'm not actually suggesting that.
"Do you even know what the Crown Estate is?"
Yup.
And it's not the private property of the Monarch and it's revenues to directly to the Treasury.
If we gave them the boot why would their be a change in that? Why would it become private revenue? Why wouldn't it continue to be owned and run by the State?
"There is PLENTY of evidence to support the fact they bring in more money."
No there's not, there's really not and Royalists can't produce it.
However it's worth noting that Republicans can't produce figures that show that they cost us far more than we get in return either.
If the figures were that big then one side or the other would be able to dig them out, so I strongly suspect that the overall costs and benefits in pure financial terms are negligible.
"Lastly, anyone fancy President Cameron & Vice President Clegg?"
If people voted for them who would you be to say that we shouldn't have them?
But personally that's why I'm not in favour of scrapping the monarchy. We'd either replace a pointless Monarch with a pointless President or we'd have someone messing in politics.
The British Constitution is something that's evolved over more than 1000 years, I'm not keen to rip it to bits over an argument from the bean counters when the sums cannot be great.
