Mikov was elected at a party congress on Saturday to replace Sergei Stanishev, who resigned earlier this month after the party’s poor showing in European elections in May and the subsequent collapse of the Socialist-led coalition government of Prime Minister Plamen Oresharski.
"We will propose to the president the date of October 5 for holding the parliamentary election," Socialist Party leader Sergei Stanishev told journalists on Friday after the main parties met in parliament.
Bulgaria’s ruling Movement for Rights and Freedoms, DPS, said it disagreed with its senior coalition partner, the Bulgarian Socialist Party, over plans to continue building the South Stream pipeline, which the EU has opposed.
The European Commission opened an infringement procedure against Bulgaria on 3 June, and asked the authorities to halt construction work in the meantime.
Less than five ministers will be replaced, said Prime Minister Plamen Oresharski in parliament after his Government survived the fourth no confidence vote on Friday morning.
He refused to say which ministers will be replaced, because he still hasn't discussed the matter with the coalition leaders Sergei Stanishev and Lyutvi Mestan.
