A file picture taken on April 25, 2014 shows Slovenian Prime Minister Alenka Bratusek, then candidate for leadership of the party, casting her ballot during the leadership vote at the Positive Slovenia congress in Brdo near Kranj, Slovenia. Bratusek said
Slovenia's prime minister has formally resigned, calling for an early vote to be held in the small EU nation next month.
Alenka Bratusek handed in her resignation to the parliament speaker Monday after announcing earlier she was stepping down. Slovenian lawmakers must also formally acknowledge the resignation.
The 44-year-old financial expert, who steered the country through euro-zone economic turmoil, withdrew after losing the leadership of her Positive Slovenia party to Mayor Zoran Jankovic of Ljubljana, the capital.
Bratusek said she cannot lead the government without the support of her party. Meanwhile, coalition partners have threatened to leave the government because Jankovic faces a corruption probe.
Bratusek has said snap legislative elections in June would be the best way out of the political troubles.
