On 9 February 2014, a Yes vote of more than 50% was obtained and the referendum to have a quota limiting immigration to Switzerland has now passed. Three referendums were held in Switzerland on this day. Voters were asked whether they approved of a proposal to impose a quota on immigration, a federal decree on the financing and expansion of the rail network and a federal popular initiative on abortion. Further referendums are planned for 18 May, 28 September and 30 November, with one to include a proposal on guaranteed income.
