The Swiss will also vote on a bill to make civilian service less accessible

GENEVA – Swiss voters will decide the fate of a divisive anti-immigration proposal on Sunday to cap the country’s population, and another referendum on restricting access to conscientious objection to military service.

Opinion polls suggest that both votes, put forward under Switzerland’s direct democracy system, could be tight.

Voting booths will open for just a few hours Sunday morning before closing at noon (1000 GMT), most of the votes having been cast in advance by post. The first results are expected by mid-afternoon.

Tensions have been running particularly high over the “No to a Switzerland with 10 million!” initiative, put forward by the hard-right Swiss People’s Party (SVP).
