London’s population is set to decline for the first time in more than 30 years, driven by the economic fallout from the coronavirus pandemic and people reassessing where they live during the crisis, according to a report.
The accountancy firm PwC said the number of people living in the capital could fall by more than 300,000 this year, from a record level of about 9 million in 2020, to as low as 8.7 million. This would end decades of growth with the first annual drop since 1988.

I actually thought London's population was overestimated for a while now, even before the lockdowns etc. Its peer cities have been losing population over the same decade: New York was revised down from 8.6 million in 2016 to 8.3 million in 2019, and is likely below 8 million now, and Paris has dropped to "only" 2.1 million .
Interesting. It's been losing parliamentary seats since the 1970s. The abandoned parliamentary review was the first one since then where it was going to gain seats, with this information I doubt that will remain the case. The government will be pleased...
Updated figures for GE electorates are now out, and the short answer is - yes, Greater London is going to gain a couple of seats in the coming review.
(lets recall that quite a few who have left recently wouldn't have been entitled to vote in one anyway)
