The Swiss federal government has confirmed a dominant performance in legislative elections by a nationalist party that seized on widespread concerns about mass migration in Europe.
Official results showed the anti-immigration Swiss People's Party collected 29.4% of the vote, an increase of nearly 3 percentage points from the previous election to the lower house of parliament, the National Council, in 2011.
The Social Democrats were a distant second, virtually unchanged at 18.8%. The pro-business Free Democrats increased by 1.3 percentage points to 16.4%.
Turnout was 48.4%. Analysts cited voter fatigue for the relatively low figure.
The result is likely to weigh heavily on National Council voting for the seven-member executive Federal Council on December 9.
