If you end up in Stratford,East Ham or Southall out west,then that is the case.Tottenham 50/50.
However all those areas like Kensington,Earls Court,Belgravia,
Knightbridge are 90% English.
Terrace house in Kensington £3.5 million,Detached £6 million.
Two bed flat in Belgravia £2.2 million average.
How can so many non British are in London, are they illegal residents and/or from EU? Sorry I am not sure to understand.
