Platinum seems a boring sort of Name for a jubilee, compared to Silvrt, Gold or Diamond. I'd not be surprised if she's still here for an 80th - that would be an Oak Jubilee. In an odd way that sounds a lot more stylish than Platinum. Maybe they'd plant lots of trees to mark it. Charles would like that.

I've never understood why it is that a reigning King's partner is Queen, but a reigning Queen's is never a King.
