Swiss voters get the chance today to decide whether to extend working rights to the ten new members of the European Union, mostly from eastern Europe.
Brussels and the government in Berne are urging people to vote ‘yes’ in thereferendum.
Voters rejected moving towards EU integration in 1992, but the government has since agreed to a series of complex deals with the bloc concerning cross-border trade and law enforcement.
Polls have been predicting a slim victory for those in favour of extending the immigration rights.
Observers say relations between Switzerland and the EU could become difficult if the voters reject the changes.
