(Bloomberg) -- Bulgariaâs three-time premier, Boyko Borissov, said heâll step aside and nominate his former foreign minister to become prime minister and attempt to form a new government after this monthâs elections. Borissov, one of Europeâs longest-serving leaders after first taking office in 2009, won the ballot but new parties that pledged to shun him over his weak fight against corruption are blocking him from a fourth term. He said Wednesday that heâll propose Daniel Mitov, his foreign minister from 2014 to 2017, to lead the next government.
