Sarah Smith was elected Labour MP for Hyndburn on 4 July 2024 with 12,186 votes (33.5 percent) and a majority of 1,687 (4.6 percent). She defeated not just a Conservative incumbent but Sara Britcliffe, the Deputy Chairman of the Conservative Party, who had taken the seat from Labour in 2019 aged 24. Hyndburn is a Red Wall seat, Labour from 1992 to 2019, and her win is part of that wall's repair.

Born around 1986 and raised in north east Scotland, where she attended Chapel of Garioch Primary and Inverurie Academy, she read law at Queen Mary University of London and then spent many years working for charities tackling youth unemployment, a Scottish raised, London educated law graduate now representing a Lancashire seat. She was a Labour councillor for Marton ward on Blackpool Council from 2023 until she resigned on becoming an MP; her vacated council seat was won by Reform in the October 2024 by-election, an early sign of the local pressure she faces.

She sits on the Housing, Communities and Local Government Committee, the Ecclesiastical Committee, and the Railways Bill committee, with APPG interests spanning miscarriages of justice, early education and childcare, and youth affairs. She has voted in 344 divisions with no whipped rebellions. She has established a "Get Hyndburn Working" group, bringing together schools, the DWP, the college and voluntary organisations to tackle unemployment, drawing directly on her charity background. Lancashire County Council is Reform led, and she has attacked it over pothole failures: the spectacle of a Labour MP fighting a Reform led county council over basic services is the defining tension of her local politics.

Smith's strengths include a law degree from Queen Mary, years of charity work on youth unemployment, the Get Hyndburn Working group showing proactive constituency organisation, the HCLG Committee matching local regeneration needs, the Red Wall recovery narrative, and a loyal voting record. Her weaknesses include a 1,687 majority (4.6 percent), a 33.5 percent vote share, no connection to the area before selection (Scottish upbringing, London education, Blackpool councillor), the council seat lost to Reform immediately after she vacated it, no ministerial office, no legislative achievement, and the Reform led county council creating a hostile local government environment. At around 38, with the law degree, the youth unemployment expertise, and the HCLG Committee, she has credible foundations. Whether the Get Hyndburn Working group produces visible employment outcomes and whether she can hold a 1,687 majority against both Reform and Conservative challengers will determine whether the Red Wall repair holds.
