"London contains by far the lowest percentage of White British people of all the UK regions, where they make up less than half of the population in two of the 32 boroughs and some areas of others. The city with the lowest White British population as a percentage is Leicester. Slough is also comparable to Leicester, whilst not being a major city[Not a city]. Outside London, the highest densities of non-white classifications are found in the West Midlands conurbation, West Yorkshire, Greater Manchester, the larger cities of the East Midlands and satellite-towns of London, such as Luton. There are also significant numbers of non-white people in most major British cities, while the far northern, western and eastern rural fringes of the UK contain the largest percentage of White British people anywhere in the UK.[citation needed]
As of 2009, every UK region has a White British majority population. There are however seven London boroughs where White British individuals represent a minority of the overall local population (including Brent 30.9%, Ealing 45.5%, Hackney 47.1%, Harrow 47.5%, Newham 32.6%, Tower Hamlets 47.1% and Westminster 49%).
Its probably a reasonable assumption that those figure are even worse by now, and its spreading out slowly but surely over the whole country.
