As an American, a large part of my impoverished experience of British accents comes from ancient BBC comedy imports on PBS. I'd very much like to identify the regional accents the following actors are using:
the farmer Maurice Moulterd in Are you being Served? Again! (aka Grace and Favour) (the second series where they're running a country inn).
Alice Tinker and Owen Newitt in The Vicar of Dibley
Onslow from Keeping Up Appearances
All four have distinct ways of speaking (not necessarily the same, but then that's the problem, I can't tell).
Which accent does each of these four use?
