Europe watches Swiss immigration vote
By Imogen Foulkes BBC News, Geneva
Swiss voters are going to the polls on Sunday in a nationwide referendum on immigration which is being watched closely right across Europe.
The proposal, from the right-wing Swiss People's Party, calls on Switzerland to abandon its free movement of people treaty with the European Union and introduce strict quotas on immigration.
Switzerland is not a member of the EU, but has adopted large sections of EU policy, including free movement and the Schengen open-borders agreement, in order to have access to Europe's single market.
Brussels has always insisted that the Swiss will not be allowed to cherry-pick only the aspects of EU policy they like.
But its successful economy, and soaring unemployment in many eurozone countries, make Switzerland a very attractive destination.

I'm a tad concerned, but overall I think this won't go ahead. We've tried it before a few times, and it's always been taken down.
