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
In the nearby counties of Berkshire, Oxfordshire, Hampshire and the Isle of Wight, it was possible to encounter comparable accents and, indeed, distinct local dialects until perhaps the 1960s. There is now limited use of such dialects amongst older people in local areas. Although natives of such locations, especially in western parts, can still have West Country influences in their speech, the increased mobility and urbanisation of the population have meant that local Berkshire, Oxfordshire, Hampshire and Isle of Wight dialects (as opposed to "accents") are today essentially extinct.
