LJUBLJANA, Rabi'II 12, 1434, Feb 22, 2013, SPA -- Slovenia's main opposition party on Friday moved to hold a "constructive no-confidence vote" next week to replace conservative leader Janez Jansa, whose majority in parliament is dwindling as parties drop out of his coalition, according to Reuters. The centre-left Positive Slovenia (PS), which earlier named its candidate for prime minister, financial expert Alenka Bratusek, filed a motion to hold the vote at an extraordinary parliament session on Wednesday. Such a vote would allow parliament to oust the prime minister and approve a successor in a single vote. Bratusek is virtually certain to be endorsed as the PS has already secured the support of other opposition parties. Jansa, whose reputation has been damaged by a corruption scandal, lost a second member of his ruling coalition on Friday when pensioners' party Desus formally quit. He is expected to lose a third party on Monday. The defections will leave him with only 30 out of 90 seats in parliament, unable to govern effectively but still clinging to power. The opposition parties agreed that Bratusek would call for a confidence vote after one year in office, which would allow parliament to oust her, triggering a snap election. A regular ballot is due in late 2015. -- SPA 20:22 LOCAL TIME 17:22 GMT www.spa.gov.sa/1080951
