CentristsThis is arguably one of the most influential wings of the Labour Party at present, as many of its proponents hold Cabinet positions. One Labour MP told The i Paper that the Blue Labour group “saw themselves as the only caucus able to take on the threat of Reform” partly due to their focus on working-class voters, immigration and family values. I think, if you want someone to appeal to wavering Reform voters, her politics could be your best bet.”Issue‑based groupsSome Labour MPs organise around specific policy priorities rather than ideology. The Labour Growth Group (LLG) and Labour YIMBY (Yes, in my back yard) caucuses focus on housing, planning reform, and economic growth, advocating ambitious housebuilding, infrastructure investment, and strategic development. Threat rating: 2/5 – While neither group is likely to directly challenge Starmer, both focus on high-profile, contentious issues.
