For those that don’t know, the City of London is the ancient Roman core of Metropolitan London.
It has its own separate police force, distinct from the Metropolitan Police that looks after the rest of London.
The City is also governed differently to the rest of England. I’m guessing this document is probably part of the reason why.
It’s the only place in the UK that’s not run on the basis of 1 person 1 vote. Instead it’s run by the City of London Corporation. It’s a city state within a city run as a corporation.
It’s ancient science fiction and weird as fuck. :P
