History

In the lead-up to the 2024 United Kingdom general election, the Labour Party of Keir Starmer committed itself to bring the passenger operations of the British rail network back under state ownership.^[2][3] Following its election win, the government introduced the Passenger Railway Services (Public Ownership) Act 2024 that received the royal assent in November 2024.^[4][5]

In September 2025, it was announced that the passenger rail services provided Govia Thameslink Railway would transfer to public ownership on 31 May 2026.^[6][7][8]
