The United Kingdom is experiencing a record-breaking exodus of wealthy individuals in 2025, with an estimated 16,500 millionaires expected to leave the country, the highest number recorded globally for a single year. This outflow has been attributed to recent policy changes, including tax hikes and the end of tax breaks for wealthy foreign residents, as well as economic instability and ongoing Brexit-related challenges. The departure of these high-net-worth individuals is projected to result in approximately £66 billion in assets leaving the UK. Analysts and reports from sources such as Forbes and Henley highlight that this trend, sometimes referred to as "Wexit," reflects a broader wealth migration driven by the UK government's tax and visa policies under the Labour administration. The loss of millionaires and billionaires raises concerns about the future investment climate and tax revenue in the country. The UK’s situation contrasts with previous years when it was a preferred destination for the world's richest, now facing the largest single-year departure of wealth ever recorded.
