This accent is probably spoken by a small minority of Britons, and whenever the topic of British accents comes up theres always somebody from outside the south of England who praises the accents of the Midlands or the North, however these accents have no credibility outside their own regions and everybody knows it.
Context in American cullture:
The 'bad guy' in American entertainment very often has a british accent like the X Men villain played by Ian McKellan or many of the characters portrayed by Anthony Hopkins. In recent years however, this accent has been seen by American girls as 'cute' when sported by persons like Jude Law, Orlando Bloom or Kiera Knightly. Since this culture emerged it has been exploited endlessly by lonely British private school boys who wish to use their accents to get laid, most notably seen in Love Actually where the character Colin ends up in bed with Elisha Cuthbert and other American girls.

The south east accent is the one most frequently heard outside of Britain in the media and in films (curse you Hugh Grant!) so people don’t really hear many different accents from across the British isles which has led to the stereotyping of the "British accent".
Saying "British Accent" is just as stupid as saying "North American Accent", in as much as "Britain" is more a reference to the land mass that contains within it the countries England, Scotland and Wales, so also North America contains The U.S.A., Canada, Mexico etc.
We here in The U.K. like to be called by our country of habitat, namely, England, Scotland, Wales, or Northern Ireland. (Please never get the Northern Irish Mixed up with Irish or any other english speaking accent.. They hate that just as much as we hate to be called British.) All of this hangs nicely around our accent. According to the country we live in, we like to be known as having English, Scottish, or Welsh accents. Keep calling us British, or saying that we have a British accent, and we'll start calling you Americans "Canadian" or even "north American". And we might even say that you sound like the Canadians, we know you'd hate that, but the thing is, we can actually tell the difference.
(PS:Northern Ireland is not officially classed as being in Britain, though the British government does rule it, just as it used to rule many other countries around the world. Thats why it is often referred to as Great Britain and Northern Ireland. Together this is referred to the United Kingdom, something that is totally different from Britain.)
All who watch the film (outside the U.S.) think: Stupid American tosser, its just a thick Yank trying very hard to do a cockney accent, and failing miserably. Plonkers.
It is not specifically "English Accent". If you want to say someone has an English Accent. Then it is common sensical to say "English Accent" as opposed to the potentially irritating generalization.
Make no mistake. I, for one, and many others like me will not let you use the term "Britsh Accent" (OR British anything else where you actually should have said English)
without some form of protest. Be it verbal or physical.
