The UK population is estimated to have grown by nearly three million between 2020 and 2025, official figures show, not by 12 million as stated by Manchester United co-owner Sir Jim Ratcliffe. In an interview for Sky News broadcast on Wednesday, Sir Jim said: The population of the UK was 58 million in 2020, now it's 70 million that's 12 million people. It had climbed to just under 69.5 million by mid-2025, an increase since 2020 of almost 2.8 million.
