Interesting stuff, which superficially I like the sound of. It's about time
this notion that London should somehow be artificially divorced from its
south east context is challenged, and this helps do just that. IMO, in
terms of transport and many other matters, the London area should be managed
as an integral part of the south east of England, not separated out into an
artificial region, with the surrounding area divided between two further
administrative regions - east and south east.
