Note that it's the 'City of London Corporation' [1] that's called for a halt. The title at the moment implies that the authorities of London as a whole have gotten involved.
Well we mean "The City known as London". Most people outside of those that live there wouldn't understand the difference between the history of Londinium and its founding all the way back to Roman times. And the "suburbs" if you will that most people would identify to be the city itself. It is much like most people don't always distinguish the boroughs of New York from the City of New York until they need to have a reason to.
TLDR: I agree, and disagree simultaneously and think that the whole rats nest of London and who controls what with things like the "Mayor" to be... stereo-typically British for lack of a better term. :)
