Sarcasm or no, I'll respond as I appear to have touched a nerve. It's still the "standard" neutralish accent but noone is really bother about accent nowadays. Even newsreaders now have regional (gasp!) Accents. The world has not yet ended. Even the BBC lets regional accents have their day!
Standard English usage is the important one, distinguishing between SE and dialects is an important thing to understand. Accent not so much.
