Cardiff South and Penarth.
Labour and Co-operative Party MP Stephen Doughty holds the seat on 44.5% of the vote — a split-council geography across 2 councils.
1 Jun 2026
Doughty is currently serving as Minister of State for Europe at the Foreign Office -- a role that has pushed him into the headlines recently over UK sanctions targeting Southeast Asian scam networks linked to human trafficking and romance fraud affecting British victims. In March 2026 he announced asset freezes and blacklisted crypto infrastructure tied to a multibillion-dollar fraud empire, drawing consistently positive press coverage on that action. His most notable parliamentary divergence came in June 2025, when he broke with his party five times on the Terminally Ill Adults (End of Life) Bill -- voting to tighten safeguards against voluntary starvation being used to meet the terminal illness threshold, and backing procedural moves the Labour majority rejected.
His voting participation sits at 45%, well below the Commons average -- typical for a minister whose departmental duties displace much of their parliamentary attendance. When he does vote, he follows Labour's line roughly 95% of the time. His stance profile shows strong alignment with workers' rights and progressive taxation, but notable scepticism on welfare expansion and business-friendly measures. His speeches lean heavily on defence (86 contributions) and economy and jobs (46), consistent with his Europe brief. He scores markedly higher than his party average on parliamentary scrutiny and assisted dying safeguards -- two areas where he has shown genuine independence.
As a minister he sits on no select committees. The high volume of culture-and-sport news articles (33, averaging neutral sentiment) likely reflects Cardiff and Penarth local coverage rather than parliamentary activity. Crime coverage scores positively, driven by the sanctions work. No data is available on his ministerial written statements or correspondence beyond what appears in parliamentary records.
