(Bloomberg) -- A plan by Switzerland’s right-wing People’s Party to cap the population at 10 million has the backing of almost half the country, according to a poll before an expected vote next year. The party, which has long campaigned against immigration, argues that too-fast population growth is overwhelming housing, transport and public services. The level of support comes despite the government urging voters to reject it, warning that strict curbs would damage the economy and prosperity as Swiss companies depend on foreign workers.
