The tough-guy premier resigned in November after his candidate was beaten by a Moscow-friendly general in presidential elections, sparking renewed political instability in the EU's poorest country, where no other party can currently form a government without the support of Borisov's conservative GERB party.
Borisovs demisionēja novembrī pēc tam, kad viņa atbalstītā kandidāte Cecka Cačeva cieta sakāvi valsts prezidenta vēlēšanu otrajā kārtā, kurā uzvarēja par prokrievisku uzskatītais ģenerālis Rumens Radevs.
