Gareth Thomas is a persistent Labour and Co-operative politician whose influence has come through specialist legislation and junior ministerial office rather than command of a major department. Elected for Harrow West in 1997, he progressed through the New Labour system and spent seven years in development and trade posts under Tony Blair and Gordon Brown. He returned to government in July 2024 as minister for services, small businesses and exports, with responsibility for the Post Office, but left in Keir Starmer's September 2025 reshuffle. He has never reached the Cabinet.

The organising principle of his politics is mutual ownership. His most distinct personal legislative achievement was the private member's bill that became the Industrial and Provident Societies Act 2002. It strengthened the safeguards applying when a co-operative or community society sought to convert into a company and made it easier to keep mutual law aligned with company law. The legislation was technical, and was later consolidated into the 2014 co-operative societies statute, but it addressed a real danger of demutualisation and asset capture. It remains better evidence of Thomas's individual effectiveness than the broad departmental achievements claimed from his earlier ministerial service.

This commitment places him on Labour's pragmatic, decentralising wing. Thomas has argued for co-operatives and mutuals as alternatives to both conventional shareholder ownership and state control, particularly in banking, housing and public services. As a former chair of the Co-operative Party's parliamentary group, he helped keep that programme connected to Labour rather than pursuing an independent political vehicle. He is also a committed European: in 2017 he defied Labour's whip and voted against authorising the Article 50 notification. That was a meaningful act of independence, although one shared with 46 other Labour MPs.

Thomas's most consequential recent responsibility was Horizon redress. The system was largely inherited, so he cannot claim to have created the compensation schemes or the legislation overturning convictions. During his tenure, however, payments accelerated sharply. By January 2025 more than £663 million had been paid to over 4,300 claimants, and by June the total across the schemes had passed £1 billion for more than 7,300 postmasters. His department also took administration of redress for postmasters with overturned convictions away from Post Office Ltd, responding to victims and the Business and Trade Committee. That was both a practical improvement and a recognition that an organisation implicated in the scandal should not control victims' claims.

The record was nevertheless incomplete. Thomas acknowledged in October 2024 that the government would miss campaigner Alan Bates's proposed March 2025 deadline for paying every claimant. In January 2025 the Business and Trade Committee described the schemes as excessively slow and poorly designed; it also found that £136 million had been spent on legal and administrative costs, including £82 million paid to Herbert Smith Freehills. A further committee report in March 2026 found continuing structural failings. Thomas deserves shared credit for faster payment and the transfer of one scheme, but not for resolving the scandal.

On late payment to small businesses, his ministry introduced a voluntary Fair Payment Code that had attracted more than 300 participating businesses by June 2025. His July Small Business Plan proposed stronger powers for the Small Business Commissioner, fines, compulsory interest and eventual limits on payment terms. These were proposals and consultations, not enacted reforms, when he left office. No measurable reduction in late payment had been demonstrated.

Thomas's record is therefore that of a capable, patient policy specialist. He has one identifiable legislative success and improved the administration of an inherited national injustice. But after almost three decades in Parliament, he has neither accumulated senior political power nor completed a reform on the scale implied by his experience. His strengths are persistence, institutional knowledge and careful work on unfashionable subjects; his limitation is that these have rarely translated into commanding authority or transformational delivery.
