Outgoing Bulgarian Prime Minister Boiko Borisov has been hospitalized with high blood pressure, officials said on Wednesday, Feb 27, adding to a sense of political limbo before an interim government is appointed to take the country to early elections, Reuters reported.

Borisov resigned last week after two weeks of sometimes violent protests by tens of thousands accusing the government of being a "Mafia" due to rampant corruption and its failure to improve living standards in the European Union's poorest state.

Demonstrators angry at high electricity prices attacked power company offices and three people set themselves on fire.

Hospital officials said on Wednesday Borisov was admitted with hypertension earlier this week, but should be discharged later in the day. A cabinet meeting due on Wednesday was postponed due the prime minister's absence.
