Bulgaria is facing fresh elections next spring after outgoing Prime Minister Boyko Borisov, leader of the largest party in parliament today refused to form a new cabinet. <br/><br/>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.<br/> <br/>Under Bulgaria's constitution, the outgoing President will hand another mandate next Thursday to the second largest party, Socialist BSP, and then pick a third party for a final attempt to avert a snap vote. The Socialists have already said they would also return the mandate and go for elections.<br/>
