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 Northern England
In some areas, it can be noticed that dialects and phrases can vary greatly within regions too. For example, the Lancashire dialect has many sub-dialects and varies noticeably from West to East and even from town to town. Within as little as 5 miles there can be an identifiable change in accent. The Yorkshire Dialect Society has always separated West Riding dialect from that in the North and East ridings.
