Glasgow Lord Provost G0.
Glasgow also has V 0 at its disposal, having inherited it when Strathclyde Regional Council was abolished in 1996.
Seems Edinburgh set the trend for '0' plates north of the border, when S 0 was specially issued for the Lord Provost's official car after they missed out on S 1 to motoring pioneer Sir John MacDonald at its initial release in 1904. (S 1 remained in the MacDonald family until last September, when it was sold for just under £400k.)
Not to be outdone, Glasgow later secured G 0 after failing to persuade the then-owner, a Mr A Anderson, MD of local car dealership James H Galt Ltd, to part with G 1.
Other Scottish '0' plates include:
HS 0 - East Renfrewshire
RG 0 - Aberdeen
SY 0 - Midlothian
VS 0 - Inverclyde
Incidentally, we have a former Lord Provost of Edinburgh to thank for the fact that the Lord Mayor of London's official car is registered LM 0. Sir James Miller was appointed Lord Mayor of London in 1964, and promptly arranged for the City of London to be issued with a '0' plate of its own. Twelve years earlier, his predecessor Sir Rupert de la Bere (or Bôre) had acquired the plates LM 1 and LM 2 to mark his appointment as Lord Mayor, but chose to retain them upon leaving office.
