i love British Accent so badly, but speaking of RP, I really don't think there are many people speak in that way, perhaps only Queen, I guess,haha,actually, i like cockney, so strong and charming!! really amazing!! but i couldn't imitate it perfectly,so i speak GA now,what a pity,but if u dont live at london or have a good native teacher,it really hard to make it, but anyway,i can speak"harry potter" with a perfect british accent,that's good enough to me.^_^
