The Swiss People's Party (SVP/UDC, led by Mr. Albert Rösti) and the Socialist Party (SP/PS, led by Mr. Christian Levrat) remained the first and second largest parties, with a reduced number of seats, taking 54 and 39 seats respectively in the 200-member National Council. The Green Party (GPS/PES, led by Ms. Regula Rytz) nearly tripled its share, becoming the third largest party, winning 28 seats, the same as the Liberals (FDP/PLR, led by Ms. Petra Gössi). The Christian Democratic People's Party (CVP/PDC, led by Mr. Gerhard Pfister), which finished fourth in the National Council elections, remained the largest party, with 13 seats in the 46-member Council of States, winning one more seat than the FDP/PLR. A record number of women were elected to both chambers: 83 in the National Council (up from 64 in 2015) and 12 in the Council of States (up from 7).

On 10 December, the newly elected Federal Assembly elected the seven-member Federal Council (the government, see note), comprising five outgoing members. The Federal Assembly also elected Ms. Simonetta Sommaruga (SP/PS) of the Federal Council as the President for 2020, who will succeed Mr. Ueli Maurer.

The 2019 elections followed climate strikes which had been taking place in the country. In September, some 100,000 people gathered in the capital Bern, pushing climate change into the centre of the election campaigning of the major political parties.

Note:
Since 1959 the Federal Council has comprised representatives of the four major parties: two seats each for the SVP/UDC, the SP/PS and the FDP/PLR, and one seat for the CVP/PDC. Following the 2019 elections, the GPS/PES said it would seek a seat at the Federal Council and nominated its leader, Ms. Rytz, but she failed to win enough support at the Federal Assembly.
