Prime Minister Boyko Borisov has hinted he is ready to stand down if lawmakers turn down the Finance Ministry's debt proposal.
The cabinet announced last week it would take on a new EUR 8 B external debt to deliver on payments of existing debt and to finance the budget deficit. A vote in Parliament is expected later on Wednesday.
"If they [the opposition] do not accept the debt... if someone tells me where to find BGN 6 B until the end of the year - because I don't know - we will grant them this opportunity even today," the website Dnevnik.bg quotes Borisov as saying hours before a cabinet session kicked off on Wednesday.
The opposition has meanwhile organized a protest in front of Parliament as the vote is nearing.
