Steel tycoon Lakshmi Mittal, one of Britain’s richest residents for decades, has quietly begun moving his financial base out of the United Kingdom, a shift that reflects growing anxiety among the country’s wealthiest families as the Labour government prepares a major tax overhaul.
According to people familiar with his plans, Mittal is relocating his tax residency to Switzerland and is expected to spend more time in Dubai, a city that has increasingly become a haven for global billionaires. While the UK has long been his primary home, the changing tax climate appears to have accelerated his decision to look elsewhere.
The Labour government’s proposal to tighten tax rules for the super-rich, including a potential exit tax and stricter treatment of global assets has unsettled several high-net-worth individuals. For many, the biggest worry is not the immediate wealth tax but the broader reach of inheritance tax, which can apply to worldwide assets if an individual is deemed UK-domiciled.
For families with complex international holdings, this has raised difficult questions about how much control the government may eventually have over future wealth transfers. Advisors say the Mittals, like many other affluent families, have been assessing the long-term implications of these changes for years, but the new political climate appears to have tipped the scales.
Mittal’s departure is especially symbolic. He has been more than just a wealthy resident, he built ArcelorMittal, the world’s largest steel company, while living in London, and once owned some of the city’s most expensive homes. His long association with the UK made him a fixture in business circles, and he has even been a donor to the Labour Party in the past.
His exit now raises broader questions: Will others follow? Can the UK maintain its appeal for global entrepreneurs if tax rules become less favourable? Economists warn that a high-profile billionaire leaving the country could send the wrong signal at a time when Britain is trying to attract investment and rebuild post-pandemic growth.
For Mittal, however, the decision appears practical rather than political. Switzerland and Dubai both offer predictable, inheritance-tax-free environments, a financial stability that contrasts sharply with the uncertainty now defining Britain’s tax landscape.
