The centre-right GERB party has a clear mandate to form Bulgaria's next government following a parliamentary election on Sunday, Reuters cited its leader Boiko Borisov as saying. "This result confirmed categorically that GERB should be the leading ruling party," Borisov said, adding that GERB would make "utmost efforts" with potential coalition partners to form a government quickly. GERB won the snap election with between 32.2 percent and 32.8 percent of the vote, exit polls showed.
