The approval of a referendum to place new quotas on immigration has thrown Switzerland's special relationship with the European Union into doubt.

The bloc's relationship with Switzerland is under review after voters narrowly backed a limit on migrants from Europe.

The Irish foreign minister said the vote was "very disturbing" and could cause "major difficulties for the movement of people in Europe".
