Not every country has a spoil system, there's probably no need to change anyone in the institutions (except those very close to Vučić in dangerous positions)

Which is a double edged sword since then it's hard to get rid of the incompetent and corrupt people when they are deeply entrenched.
Every ministry still has a team of people that are there based on their affiliation with the currently elected government. Of course I don't think they need to replace every clerk.
