The still White(r) parts in the centre are the older layers of the city (before the mid 19th century).
London used to be almost only north of the Thames. The South bank of the river was swampy and only got developed in the 20th century. I guess there was room there for blacks.
Jeets are everywhere but are concentrated in the two blobs in the west and a large stripe in the east (this is the part that is called East London, the lilly White parts on the right edge are already semi rural but technically in the Greater London area). Those used to be the industrial worker areas. As we deindustrialized and imported jeets, they moved there because it was cheaper and half empty while the poorer White Brits left London for the rest of the country.
Keep in mind there are less than half as many British people in London today than fifty years ago. Not proportion, raw numbers. While our demographics aren't explosive we haven't divided by two in that time frame, basically all poor English people left the city as industries closed down or were decentralized. The fact you had to live with jeets around only made people leave faster making even more room for the new quintessentially British. There is no reason to live in London if you don't have a high paying job, so there's a near 1-1 relation between old industrial areas and diversity today.
