"Ostensibly it's the equivalent of a local council, responsible for a small area of London known as the Square Mile. But, as its website boasts, "among local authorities the City of London is unique". You bet it is. There are 25 electoral wards in the Square Mile. In four of them, the 9,000 people who live within its boundaries are permitted to vote. In the remaining 21, the votes are controlled by corporations, mostly banks and other financial companies. The bigger the business, the bigger the vote: a company with 10 workers gets two votes, the biggest employers, 79. It's not the workers who decide how the votes are cast, but the bosses, who "appoint" the voters."
"As Nicholas Shaxson explains in his fascinating book Treasure Islands, the Corporation exists outside many of the laws and democratic controls which govern the rest of the United Kingdom. The City of London is the only part of Britain over which parliament has no authority. In one respect at least the Corporation acts as the superior body: it imposes on the House of Commons a figure called the remembrancer: an official lobbyist who sits behind the Speaker's chair and ensures that, whatever our elected representatives might think, the City's rights and privileges are protected."
