This reform, strongly backed by the centrist Union of Christian and Centre Democrats (UDC), proposed a 4% threshold before a party gained any seats, and a majority bonus of at least 340 seats for the winning coalition, the total votes for each coalition being the sum of the votes of those coalition parties which had won at least 4% of the national votes.
