Former UK health secretary Wes Streeting says the current tax system is unfair and penalises work, and he proposes a “wealth tax that works” as part of his pitch ahead of a potential Labour leadership bid. Multiple reports say his plan would raise up to £12 billion per year. Streeting, who recently resigned from Keir Starmer’s cabinet, argues for reform that equalises taxation on income and capital gains. Coverage including details from BBC discussions says the approach would involve changes to capital gains tax so that gains from selling assets are taxed using income-tax style bands, rather than the existing 24% rate that applies to higher earners in the current financial year. He also suggests closing loopholes that allow some people to present earnings from work as capital gains to reduce tax. The proposals include a tax-free allowance described as £3,000, with tax applying above that threshold at rates aligned to income bands of 20%, 40% and 45%. One report notes Treasury chief secretary Lucy Rigby rejects the idea, arguing that wealth is already taxed and that recent budgets aim to keep taxation progressive and fair.
