This is the largest finding in the section. Henley & Partners — the origin of nearly every "X thousand millionaires left Britain" headline for three years — abandoned its millionaire headcount in the 2026 report and replaced it with a score out of 100. The Financial Times found its numbers failed standard forensic accounting tests and were "highly likely to be fabricated"; Dan Neidle's analysis showed digits ending in 0 and 5 wildly over-represented and UK millionaire figures overstated by roughly 100% against ONS and HMRC data. The datapoint that replaced the UK figure is applications to Henley's own migration services. Henley sells residency-by-investment. Meanwhile actual HMRC statistics published 30 July show the non-dom tax take rose 9% to £13.6bn and departures fell.
