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, marking a shift to the political right.<br />Official results released Monday showed that the anti-immigration Swiss People's Party collected 29.4 percent 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.<br />The result was likely to weigh heavily on National Council voting for the seven-member executive Federal Council on Dec. 9.
