Ha ha Garage Joe,
On the face of it, it seems a bit absurd to query the guest list of something as irrelevant as the royal wedding. They are supposed to be above politics. They've shown themselves to be very much in the Tory camp.
I think the institution should be abolished. I see them as nothing more than spongers and promoters of class superiority.
I'm a left winger and I despise everything they represent. IMO, no left winger can criticise Cameron's advantages and networking while supporting the monarchy. The monarchy is a throwback to feudalism that is only popular because of their celeb activities.
Likewise, no laissez faire right winger can talk about 'no such thing as a free lunch' and the virtues of a meritocracy while supporting the benefit scrounging royals.
