(ANSA) - BELGRADE, MAY 12 - In Slovenia, the law on supplementary pensions for extraordinary artistic merits, which was approved by Parliament in January, was rejected on Sunday in a referendum called by the conservative opposition. Approximately 26% of the electorate, or just under 440,000 people, voted. Over 92% of voters, or more than 403 thousand votes, opposed the law, exceeding the required quorum by about 100 thousand units. According to the most recent National Election Commission data, slightly more than 32,000 people voted to keep the law, with 3,000 ballots declared invalid. The main opposition party, the Slovenian Democratic Party (SDS, conservative), proposed the referendum initiative after framing the brief election campaign as a referendum on Robert Golob's government.
