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.
Essex dialect
The Essex dialect is a traditional dialect mainly confined to the north and the east of Essex. It is similar to some forms of East Anglian English, including both the Suffolk and Norfolk dialects, but has its own peculiarities. With rapid urbanisation in the twentieth century, as well as the impact of the London overspill, Estuary English, a milder form of the London accent predominant largely along the Thames Estuary and thus the name, has become common, mainly in the southern portion of the county. As a result of the growing London influence, the usage of rural accents everywhere and the rural Essex dialect is now normally, but not always, confined to older generations in some of the areas affected and the dialect itself stands in a vulnerable state in those affected parts of the county. Elsewhere in Essex, the dialect and rural accent continues.
