The Swiss People's Party, also known as the Democratic Union of the Centre, is a national-conservative and right-wing populist political party in Switzerland. Chaired by Marcel Dettling, it is the largest party in the Federal Assembly, with 62 members of the National Council and 6 of the Council of States.

Right-wing populism, also called national populism and right-wing nationalism, is a political ideology that combines right-wing politics with populist rhetoric and themes. Its rhetoric employs anti-elitist sentiments, opposition to the Establishment, and speaking to or for the "common people". Recurring themes of right-wing populists include neo-nationalism, social conservatism, economic nationalism and fiscal conservatism. Frequently, they aim to defend a national culture, identity, and economy against perceived attacks by outsiders. Right-wing populism has remained the dominant political force in the Republican Party in the United States since the 2010s.
