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 kritikovao prethodnu koalicionu vladu, koju su vodili socijalisti, zato što nije pomenula dodatne troškove vezane za savetodavne usluge, plaćanje kreditnih usluga i infrastrukturu, prilikom promovisanja projekta, uz ukupne troškove u iznosu još 2,5 milijarde evra.
