A Swiss aircraft is seen at Cointrin airport on the border with France (front) and Switzerland in Ferney Voltaire near Geneva April 28, 2014. Switzerland will vote on November 30 on an initiative from the group Ecopop which proposes a cap on the number of immigrants. The group says it is motivated by concerns about a lack of living space exerting too much pressure on the land and natural resources, rather than by opposition to foreigners. It proposes limiting immigration to just 0.2 percent of the resident population, equivalent to 16,000 people per year. This would represent a cut of more than 75 percent in annual net immigration from current levels.
