London
There are many accents traditionally associated with London. The most well known of the London accents long ago acquired the Cockney label from London's East End, which is heard both in London itself, and across the wider South East England region more generally. The accent of a 21st-century Londoner varies widely; what is becoming more and more common amongst the under-30s however is some fusion of Cockney with a whole array of ethnic accents, in particular Caribbean, which form an accent labelled Multicultural London English (MLE). The other widely heard and spoken accent is RP (Received Pronunciation) in various forms, which can often be heard in the media and many of other traditional professions and beyond, although this accent is not limited to London and South East England, and can also be heard selectively throughout the whole UK amongst certain social groupings. Since the turn of the century the Cockney dialect is less common in the East End and has 'migrated' east to Havering and the county of Essex.
English language in England
The accent of English English best known to people outside the United Kingdom is that of Received Pronunciation (RP), though it is used by only a small minority of speakers in England. Until recently, RP was widely considered to be more typical of educated speakers than other accents. It was referred to by some as the Queen's (or King's) English, or even "BBC English" (because for many years of broadcasting it was rare to hear any other accent on the BBC). These terms, however, do not refer only to accent features but also to grammar and vocabulary, as explained in Received Pronunciation. Since the 1960s regional accents have become increasingly accepted in mainstream media, and are frequently heard on radio and television. RP is also sometimes called an "Oxford accent"; the Oxford English Dictionary gives RP pronunciations for each word, as do most other English dictionaries published in Britain.
