I have made the point in the past that I think the term 'British English' is an unfortunate one. For many reasons I prefer the term 'Received English' which parallels the idea of 'Received Pronunciation'.
I feel that my view is underlined by the tragic Foley case. The person who is alleged to have executed Foley has been widely reported as 'having a British accent'. What I think they mean by this is that he speaks English using Received idioms and in a Received Pronunciation.
There a multitudes of people across the world, who are not necessarily British, who use received English. Aung San Suu Kyi, for example speaks with a received accent, as do a lot of the Pakistani ruling class.
The idea that Received English and pronunciation should be exclusively associated with Britain is absurd. And in this instance it has tarnished Britain in that it associates us with the brutal Foley killing.
I feel strongly that the abbreviation BrE should be changed to RecE.
