The Celtic Republic – consisting of Brittany (Breizh), Cornwall (Kernow), Ireland (Éire), the Isle of Man (Mannin), Scotland (Alba), and Wales (Cymru) – holds elections every four years under a system of mixed-member proportional representation, with half of the seats awarded by local first-past-the-post and half as levelling seats based on the party vote. For the past four years, a grand coalition of Christian democrats, socialists, and liberals has governed the country. Cost of living, immigration, and foreign relations all weigh on the electorate’s minds as they choose the next government.
The scenario itself is downloadable here.
You’ll want to use the seat calculator available here (the file also contains background information about the scenario):
