Re: And this ladies and gentlemen...
Ummm yeahhh, except you do. Reading DVLA office is currently (or was, as of a couple of weeks ago) issuing "RO" initial letters. A mate just bought a new Jag e-car and its registration starts with RO 70 - and incidentally, looking at the photos, there is absolutely no discernible difference between the "O" and the "0" on his number plates.
