Mr Sipila's Centre Party has been in a centre-right coalition government since 2015. Since a 2017 re-negotiation, the government has been formed of the Centre Party, the National Coalition, and Blue Reform. The opposition Social Democrats have taken the lead in recent polls by several percentage points. So basically the Finnish Righties fucked up, just like they do everywhere else.
You do know that the Centre Party, the National Coalition, and Blue Reform that formed the coalition government....not one of these would be considered "rightists" by American standards.
I can only assume based on this post that this is a whiskey thread and you're two bottles in. What happened here is one of the common features of a parliamentary democracy, not a bug.
