Harry Potter and British dialects

[lord of the mark]

Anyone here now what the regional dialects spoken by the different characters in the Harry Potter books are? Whos speech is closest to "RP"? Whats Rons dialect? I presume McGonagal is lowland Scotland? Whats with Hagrid?

Note im interested mainly in the books, not the movies, except for Hagrid, where I seem to be under the impression the movies changed it.

RP is BBC Newscasters English. Pretty much.

The rest, I don't know, cos I don't like the Potter much.

In the books, only Hagrid and McGonagal have accents much, as I recall. I read McGonagal as educated Edinburgh, Hagrid as Somerset, but his accent in the books is fairly generic "accent".

Ottery St Catchpole (Weasleys and Luna) sounds Oxfordshire/Warwickshire to me, Little Whinging (Harry) is Surrey, Hermione is also fairly home counties, I think. Dean is London, so probably has some kind of cockneyish accent. Seamus has an Irish accent.

Hermione probably has the most RPy accent, although without the 1950s enunciation. The Malfoys and Snape would perhaps be properer if they didn't drawl all the time.

Received Pronunciation.

Incidentally, if you wanted to cast members of the Goon Show as Harry Potter characters, I would suggest the following:
Harry - Neddy Seagoon
Ron - Eccles
Neville - Bluebottle
Hagrid - Major. Bloodknock
