Can I be hideously pedantic and point out that British would include Scottish and I think you mean English?
Also, that there are quite a few Scottish and Irish accents, and I don't think many of them really classify as dialects rather than accents, although that's a subjective judgement, of course, and RP and Cockney are not really dialects either, or at least, I wouldn't classify them as such. (AND, while I'm on the subject, interesting point: both are pretty behind the times - Cockney is being wiped out by Jafaikan (MLE) and RP is being polluted by Estuary. Although the dividing line between Cockney and Estuary is a bit vague, so maybe Cockney is finally winning really.)
I'm sorry for the annoying pedantry! English within the UK is fascinating, man.
