Basel, Switzerland, Safar 8, 1436, Nov 30, 2014, SPA -- Swiss voters are set to decide Sunday whether immigration should be drastically reduced, alongside votes in separate referenda on the status of gold reserves and tax benefits for foreigners, dpa reported. A conservative ecological group has proposed limiting net immigration to less than 17,000 per year, from the current level of 100,000. This is the second referendum on this topic since February, when voters narrowly approved introducing limits and quotas for all foreigners, including EU citizens. --SPA 12:14 LOCAL TIME 09:14 GMT www.spa.gov.sa/w
