Federal elections were held in Switzerland on 30 October 1881. The Radical Left remained the largest group in the National Council, regaining the majority they had lost in 1863.[1]
Electoral system
The 145 members of the National Council were elected in 49 single- and multi-member constituencies using a three-round system. Candidates had to receive a majority in the first or second round to be elected; if it went to a third round, only a plurality was required. Voters could cast as many votes as there were seats in their constituency.[2] There was one seat for every 20,000 citizens, with seats allocated to cantons in proportion to their population.[2]
The elections were held under the new Federal law concerning the elections of National Council members passed on 3 May 1881. The number of seats was increased from 135 to 145 following the 1880 census, and the number of constituencies from 48 to 49; Bern and Zürich both gained two seats, whilst Appenzell Ausserrhoden, Basel-Stadt, Geneva, Schwyz, Ticino and Vaud all gained one.
