The last census, in 2011, revealed that during the previous decade, the capital's white British population declined by 620,000.
That's an average annual drop of 62,000.
New figures from the Office for National Statistics show that 340,498 people left London in 2018 for other parts of the UK, whilst only 237,270 moved in - a net loss to the capital of 103,228.
We'd bet that the far greater part of the exodus is white Britons fleeing repopulated neighbourhoods, BME stab gangs, the threat of jihadi terrorism, and other manifestations of 'vibrant diversity'.
Which if true (the next census in 2021 should tell us) means that white flight out of London is accelerating faster than even we would have anticipated.
