Well, its like any Country, we have different accents.
For Example, if you live in good old Liverpool you would be classed as a Scouse.
Certain Areas of London.... you know..the horrible bad D-ick Van Dyke impression of a cockney
I live in the north east and have a maccam* accent
I cant really describe it..but its more heavy sounding..more rough* if you like when compared with the typical Agatha Christie English accent*
