Background
Anthony Slaughter is the leader of the Wales Green Party, contesting the 2026 Senedd election with the party in position to win Senedd representation for the first time. YouGov's Senedd MRP projected the Wales Greens at 10 seats, enough for the party to act as a kingmaker in Coalition negotiations. Slaughter declared publicly that Wales Greens are "ready to be kingmakers" — a statement that immediately complicated Coalition arithmetic for both Plaid Cymru and Welsh Labour.
Slaughter has led the Wales Green Party through a period of significant growth aligned with the wider UK Green surge under Zack Polanski's national leadership. A Plaid-Green Coalition would reach 53 seats, four above the 49-seat Senedd majority threshold, making Slaughter's party the potential difference between a Plaid majority government and a further period of instability.
The alternative Coalition path — Plaid-Labour — would yield 55 seats but would require Welsh Labour to accept a junior role after suffering its worst projected results since devolution. Slaughter's positioning means Wales Greens hold leverage in either scenario, a stark contrast to their historical irrelevance in Senedd elections before the 2026 cycle.
