The UK government is preparing legislation that would allow the full nationalisation of British Steel, marking one of the biggest industrial interventions in Britain for years. Prime Minister Keir Starmer said on 11 May 2026 that ministers would take powers to bring the company fully into public ownership after efforts to find a private-sector solution failed.

British Steel’s Scunthorpe operations have been treated as strategically important because they support sectors such as rail, construction and automotive manufacturing. Reuters reported that the business had already been taken over by the government in April 2025 to prevent closure under its Chinese owner, Jingye, and that support costs were projected to reach about £615 million by June 2026.

Starmer said any full nationalisation would be judged through a public-interest test tied to national security, critical infrastructure and wider economic value. Ministers have not completely ruled out future private investment, but the current position is that no proposed deal offered sufficient value to taxpayers.

The announcement also lands at a tense political moment. Starmer is facing internal pressure over his leadership, while markets are already reacting nervously to wider uncertainty in UK politics. Reuters reported on 12 May that long-dated UK borrowing costs rose sharply and sterling weakened as investors weighed the political risks.
