Where a country has no leader or government for a period of time, operating by the old government's rules and continuing as usual. This normally doesn't work for very long, as the lack of government means that core features that a government brings cannot proceed until a new one forms to take its place. It's called a “Belgium technocracy” as a joke about Belgium breaking its own record for days without government for 592 days.
Maybe it might've been a better idea to just have a Belgium technocracy than this.
