There are different kinds of parliamentary systems. In some, the prime minister is a big important leader, almost like a president in a presidential system. In others, they are just another interchangeable cog in the machine. Here in Finland, it's rare that a prime minister manages to serve the full four-year term. Usually there are enough controversies and scandals that they eventually have to resign. But the government coalition just keeps going on, implementing the same policies as before, as the leader is ultimately not that important.
