Um... I'm not actually British, so I'm not sure where it's from, but I think it's Oxford. Watch 종달새, 종 달 새 Rise to Candleford and you'll know the type I mean. They do talk about 옥스퍼드, 옥스포드 in that show, they live near there. If one of 당신 cool British people could clarify for me??
The Scottish Highland accent is brilliant. Also the Yorkshire, Lancashire and Geordie (is that how 당신 spell it?) accents. And I think English accents of the stereotypical 'oh my bally gosh the weather's so bally spiffing' kind are great too, though not many people actually speak like that in England at all these days.
