The official centre of London, from which all mileages are supposedly
measured has been the statue of Charles I in Trafalgar Square for quite
a while now. Presumably, for the pedantic, from the top of his head or
where his body meets the saddle. (Phew! I managed to avoid saying a
rude word. :-) )

That's precisely what we are discussing, but in the absence of any
evidence of who/what made it official (and when).
