Borisov je odlučio poduzeti taj potez bez presedana u njegovoj zemlji nakon što su mu je četvero od pet članova njegovog kabineta u zadnjih otprilike mjesec dana iznijelo zabrinutosti po pitanju problema s projektima u Slivenu, koji vodi gradonačelnik Yordan Lechkov.
Borisov said he decided to take that unprecedented move for his country after four or five members of his cabinet had shared with him in the past month or so their concerns about problems with the projects in Sliven, which is run by Mayor Yordan Lechkov.
