Wes Streeting Pitches Capital Gains Overhaul in Labour Leadership Bid

BBC Business reported Thursday that former Health Secretary Wes Streeting has outlined a capital gains tax reform as his opening policy salvo in a prospective Labour leadership campaign. Streeting described the plan as a “wealth tax that works” and estimated it could generate around £12bn annually for the Treasury.

Streeting’s Capital Gains Tax Proposal

The core of the plan would align capital gains tax rates with the three existing income tax bands of 20%, 40%, and 45%. Under Streeting’s model, a taxpayer’s capital gains band would be determined by combining total income with asset profits. He also wants to close arrangements that allow earned income to be reclassified as capital gains, reducing overall tax liability.

Streeting argued the current system unfairly punishes employment income while favouring asset holders. He did, however, carve out a concession for genuine risk-takers. Entrepreneurs who build companies from the ground up would qualify for reduced rates under the proposed framework.

For context, the current annual capital gains tax-free allowance sits at £3,000. Higher and additional-rate taxpayers currently pay 24% on gains above that threshold. A 2024 analysis by the Centre for the Analysis of Taxation estimated that broadly reforming capital gains tax could raise up to £14bn per year.

Background: Resignation and a Leadership in Flux

Streeting quit the cabinet last week after scores of Labour MPs publicly urged Prime Minister Sir Keir Starmer to step aside. He told BBC Business he had informed Starmer directly, in a Downing Street meeting the day before his resignation, that he intended to challenge him for the party leadership.

Under current Labour rules, any formal leadership contest requires the backing of 81 MPs. Streeting acknowledged he held back from immediately triggering a challenge, partly because Greater Manchester Mayor Andy Burnham had not yet secured a route back into Parliament. That changed when MP Josh Simons announced he would vacate the Makerfield seat, opening a by-election path for Burnham.

Brexit and Other Policy Positions

Beyond tax, Streeting used the same BBC interview to revisit his stance on European Union membership. He described Brexit as a “catastrophic mistake” but said rejoining would require it to become the settled democratic will of the country first. He also distanced himself sharply from former Labour figure Lord Peter Mandelson, who was removed as UK ambassador to the United States last year, saying he “would not have appointed” him and considered Mandelson to have “no future in public life.”

The interview marks Streeting’s most detailed public pitch yet, framing economic fairness as the central argument for his potential candidacy.
