Efforts are underway by UK Green Party co-leader Zack Polanski—a London Assembly member known for his pro-worker, left-wing platform—to persuade trade unions to shift political funding away from the Labour Party toward the Greens. The move reflects growing frustration among some union members who feel Labour has not gone far enough on workers’ rights and economic justice. While most major unions remain historically aligned with Labour, internal debates suggest some openness to diversifying political support. The situation highlights a potential shift in traditional labor-party alliances and increased competition for union backing in UK politics.
