'As much as I might like the idea of a London city state, I'm not seriously talking about independence today. I am not planning to install border points on the M25.
'But on behalf of all Londoners, I am demanding more autonomy for the capital - right now.
'More autonomy in order to protect London's economy from the uncertainty ahead, to protect the businesses from around the world who trade here and to protect our jobs, wealth and prosperity.' - Sadiq Khan.
Take from that what you will, I see it as yet another tacit admission that Khan is putting his own agenda first. And then there is the seemingly open-ended nature of that statement, "I'm not seriously talking about indepdence today" - maybe tomorrow then?
EDIT: He also said this:
"Mr Khan said that he would not 'criticise other cities for trying to pinch our business' - 'that is what you do if you are the leader of a city'
While he's probably not wrong, I think it's interesting that he describes the role of the mayoral office as the role of a thief.
