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.
Borisov je kasnije kritizirao bivšu koalicijsku vladu, koju su predvodili Socijalisti, jer nije spomenula dodatne troškove vezane za savjetodavne usluge, plaćanje kreditnih usluga i infrastrukturu, prigodom promicanja projekta, u ukupnom iznosu još 2,5 milijardi eura.
