Indian-origin steel billionaire Lakshmi N Mittal has relocated from London to Dubai ahead of anticipated UK tax increases by the Labour government. The ArcelorMittal founder, valued at £15.4 billion ($19.4 billion) & ranked Britain's eighth richest person, joins other wealthy individuals departing primarily over inheritance tax concerns. While the UK imposes 40% inheritance tax on worldwide assets, Dubai levies no such tax. The exodus reflects tensions between revenue needs & competitive pressures to attract global wealth, raising questions about policy effectiveness when billionaires can easily relocate.
