I want to know the answer to the following question:
Which centres of Switzerland mostly rejected the quota system for foreigners?
All the background I'm provided with is that "On 9 February 2014, Swiss voters narrowly approved by 50.3% a ballot initiative launched by the national conservative Swiss People's Party (SVP/UDC) to restrict immigration, and thus reintroducing a quota system on the influx of foreigners.". Is that enough to answer the question?
Answer: no
