Prime Minister Ivan Kostov evaluated the ruling of the UDF as the most successful mandate in the newest Bulgaria`s history. The UDF did not do a single fatal for Bulgaria mistake, neither in its economic development, nor in terms of foreign policy, PM Kostov said during his pre election visit to Vidin, North East Bulgaria. He stated that the priority projects in the region are the construction of Transport Corridor IV, Danube Bridge-II and Petrohan tunnel. Oposite to Kostov, other parties, mainly the leftist strongly critisize what the government had achieved for the 4 years term in power. The critics are mainly focused on the slow privatization process, corruption and unemployment, which is one of the highest in Europe, up to 18% average.
