London gets its own way, with its own affairs, a lot - it already has a mayor, an elected assembly, and its own transport governance.

You listed offices, but not powers. Those bodies do not really have any substantial powers.

The GLA is not a legislative body at all.

The mayor is responsible for transport and, uhh, that's about it.

This kind of pointedly naive questioning -- starting the conversation over at zero -- is an extremely unhelpful "discussion" (debate) tactic, and is really annoying to boot.

Fair enough. I've edited it.

p.s. FWIW I don't think you should be downvoted for this comment. You were right.
