Borisov je kasnije kritizirao prethodnu koalicionu vladu u zemlji pod vodstvom Socijalista što nije kod promocije tog projekta spomenula dodatne troškove vezane za konsultantske usluge, plaćanja za servisiranje kredita i infrastrukturu, koji troškovi ukupno iznose još 2,5 milijardi eura.
Borisov later criticised the country's previous Socialist-led coalition government for failing to mention extra costs associated with consulting services, loan service payments and infrastructure when promoting the project, costs totaling another 2.5 billion euros.
