"There is no such thing as a British accent"
Absolutely correct.
All this hogwash about Scot, Liverpudlian, Cockney is just silly.
Anybody who lives in this age knows that what we colloquially call a "British" accent is used by all them foreigners.
Ever see a movie with foreigners talking English?
It dosn't matter if their "German" or "Arab" or even "Chinese", they all have the same funny way of talkin. Even those guys from Lord of the Rings all had the same accent. Not one of them claimed to be British.
Hell they don't even speak English in England, try walking into a bar, excuse me "pub" in merry ole' and order a cheeseburger and a Bud. They look at you like you've got three heads.
But they do have compassion for their disadvantaged, if your out and about you'll often hear one of them remark "nice bum" to a round of general agreement. We hardly ever compliment our homeless like that here.
