Swiss voters were forecast to reject a referendum proposal that foreign law-breakers be deported, according to initial projections from an exit poll by Swiss broadcaster SRF on Sunday.

A yes vote could have further complicated Swiss relations with the European Union, Switzerland¡¯s biggest trading partner, as it tries to reconcile a 2014 referendum backing quotas on EU workers with Brussels.

¡°The trend has clearly gone in the no direction,¡± Claude Longchamp of the research and polling institute said of the vote on Swiss television. ¡°We are definitely seeing less than 45 percent of the vote in favor.¡±

Of four referendums Sunday, the immigration vote was the main issue.

The proposal from the anti-immigration Swiss People¡¯s Party (SVP) would have subjected any foreign resident to automatic deportation if convicted of a crime from murder to speeding.

Under the SVP¡¯s draft law, foreigners would have been automatically deported after completing their sentences for serious crimes like murder, rape and armed robbery, or for two lesser offenses committed within a 10-year span such as speeding or burglary.

In the other referendums, voters were seen supporting the construction of a second tunnel through the Gotthard mountain range, a main north-south transit route.

Voters were also projected to reject a proposal to ban trading in agricultural derivatives.

There was no clear trend in a vote on whether to abolish a tax disadvantage for married couples and civil partnerships, SRF said.
