While I was in Estonia this past summer, I heard about an electoral reform in Finland, possibly involving the adoption of a national compensation tier. Perhaps this was in response to some of the unequal treatment of parties in the seat allocation in the “photo Finnish” election of 2007, as I wrote about at the time.
I do not have details of the proposed reform, or certainty that it has even been enacted. Perhaps a reader knows.
Thanks to Suaprazzodi in the Brazil thread for the reminder.
