Prominent Labour donor Dale Vince has criticized wealthy Britons threatening to leave the country over potential tax hikes, telling them to "f*** off" as they contribute little to the UK if motivated solely by low taxes. Vince, who has donated £5 million to Labour, believes a fairer tax system is necessary and that those who prioritize low taxes should leave. The Chancellor is expected to announce tax increases in the upcoming Budget to address a £40 billion deficit, potentially including higher capital gains tax and inheritance tax reform, amid reports of over 6,000 millionaires planning to leave the UK for the EU due to impending tax changes.
