What does RP stand for?

I hope Rhubarb doesn't mind my jumping in here. RP is an abbreviation of Received Pronunciation, "The Queen's (Monarch's) English." At least here in NZ it was often referred to as "BBC English" from the days when RP was the only accent allowed by that broadcaster. RP is the pronunciation mocked around the world as the preserve of the pompous and pretentious, with the unfortunate consequence that whose for whom it is natural are often victimised.
