Stephanie Peacock is the Labour MP for Barnsley South and Minister for Sport, Tourism, Civil Society and Youth. Born in Birmingham in 1986, she read History at Queen Mary University of London and took a master's at University College London, a more substantial academic foundation than "history teacher" alone implies. A Labour member since her teens, she came to Parliament with unusually deep party machinery experience: four years on the National Executive Committee and a decade on the National Policy Forum, the party's policy-making body. She worked for the Black Country MP Sylvia Heal, then as a trade union education officer training activists across northern England, and spent four years as a GMB Political Officer.

She has been Parliamentary Chair of Hope not Hate, the anti-fascist campaign, chairs the APPG for Industrial Heritage and co-chairs the APPG for Veterans. Her record is not as thin as is sometimes claimed: she campaigned successfully to raise the maximum sentences for causing death by dangerous driving, and led the campaign for justice for retired miners, demanding an end to the government taking from miners' pensions, a sum she puts at over £4 billion. Both are concrete outcomes.

She was first elected for Barnsley East in 2017, succeeding Michael Dugher, and won the new Barnsley South in 2024 with 16,847 votes (46.7 percent) and a majority of 4,748 (13.5 percent), with Reform UK second on 33.2 percent. She resigned as an opposition whip in March 2019 after defying the party to vote against a second referendum amendment, understanding that 71 percent of Barnsley had voted Leave. Since July 2024 she has held her ministerial brief, retitled from Sport, Media, Civil Society and Youth to Sport, Tourism, Civil Society and Youth in September 2025 as the portfolio expanded.

Peacock's strengths include a Queen Mary and UCL education, four years on Labour's NEC and a decade on the National Policy Forum, the Parliamentary Chair of Hope not Hate, the death by dangerous driving sentencing change, the miners' pension campaign, the Industrial Heritage APPG chair, the 2019 referendum resignation showing local understanding, and her ministerial brief. Her weaknesses include a 4,748 majority (13.5 percent) with Reform at 33.2 percent, the Sport and Tourism brief being structurally low profile, no major legislative achievement from ministerial office yet, and a Barnsley South Reform vote that means the seat is no longer safe. At 39, she has more party institutional experience than many ministers twice her age. Whether the dangerous driving and miners' pensions campaigns and the Sport and Tourism brief produce visible outcomes for Barnsley will determine whether her career develops beyond the ministerial machinery room.
