Swiss voters will decide on Sunday whether to back a controversial proposal to cap the country’s population, in a closely watched referendum that has sharply divided opinion across political and economic lines. The vote, part of Switzerland’s system of direct democracy, is expected to be tight, with polling suggesting no clear outcome ahead of the ballot.Also Read: Why Switzerland is voting to cap its population at 10 million Voting booths will be open for only a few hours before closing at noon (1000 GMT/3:30 PM IST). Most ballots had already cast by post, while the first results are expected by mid-afternoon. The far-right Swiss People's Party (SVP) has put forward the initiative, which is called "No to a Switzerland with 10 million!."

Here's all you need to know:

The proposal seeks to prevent Switzerland’s population from exceeding 10 million (one crore) before 2050.

Its population currently stands at around 9.1 million (91 lakh), up from 7.3 million (73 lakh) in 2002 and 8.3 million (83 lakh) a decade ago.

More than a quarter of the population (27%) is foreign-born, making immigration a key driver of growth.

Critics argue the measure could hurt industries that rely on foreign workers and strain Switzerland’s ties with the European Union (Switzerland is not a member of the bloc).

If the measure is adopted, the Swiss government could be ultimately required to terminate its free movement of people agreement with the EU, which provides Switzerland with most of its workforce.

However, SVP, Switzerland’s largest political party, argues that "drastic measures" are needed to curb what it calls “mass immigration.”

The party blames immigration for a range of challenges, including housing shortages, rising rents, overcrowded trains, and traffic congestion.

Despite broad opposition from the government, parliament, and business groups, the proposal has reached a nationwide vote through Switzerland’s system of direct democracy.

Under Swiss law, any initiative that gathers at least 100,000 signatures from eligible voters within 18 months can be put to a public referendum.

Opinion polls suggest the referendum could be closely contested, though recent surveys indicate that opposition to the proposal has gained a slight edge.

According to CNN, citing pollster gfs.bern, 52% of respondents oppose the population cap, giving the "No" camp a narrow lead ahead of Sunday's vote.

Military service referendum Swiss voters will also decide on a referendum challenging a parliamentary bill that would make civilian service harder to access. The proposal comes as European countries seek to strengthen their armed forces amid heightened security concerns following the Russia-Ukraine conflict. Switzerland has compulsory military service for men, though those who object on conscientious grounds can opt for civilian service instead. The government argues that a growing number of people choosing civilian service has become a concern, while opponents warn the changes could undermine an established alternative to military service. Polls suggest that here, too, the vote is likely to be close.
