About a million britons moved to europe in 2020 alone. That’s an insane brain-drain and capital leaving the country. At the same time immigration to the UK and working as a non UK citizen has been made harder. The long-term effects will be felt 5-10 years from now and millenials + zoomers will be the ones paying for the boomer’s choices. I don’t know any official numbers since 2020 but the majority of people leaving the UK settled in Germany or Spain.
