Storting. Later, Venstre advocated universal suffrage for men, which was achieved in 1898, the break-up of the Swedish-Norwegian Union, which happened in 1905, and universal women's suffrage, which was introduced in 1913. In the first decades after 1884, Venstre formed several governments, interspersed with periods of Høyre-governments. Six different Prime Ministers of Norway have come from Venstre, all of them before 1935. With the growth of the Labour Party, Venstre gradually lost ground. The election of 1915 was the last in which Venstre was the largest party and won an outright majority in the Storting. Venstre was further weakened with the formation of Bondepartiet (the present day Centre Party) in 1920, and Christian People's Party in 1933, both of which were formed partly by former Venstre members. After World War II, Venstre has been part of five coalition governments, the most recent one being Solberg's Cabinet from 2018. A dispute over Norwegian membership in the European Community, now the European Union, made the party split up at Røros in 1972, with the people favoring EC membership departing, and forming the Liberal People's Party. These included the party leader, Helge Seip, and 9 of the 13 members of parliament. Since then, Venstre has been a fairly small party. The parliamentary group was reduced to two after the 1973 election. In 1974, Venstre elected the first female leader of a political party in Norway, Eva Kolstad. Election results continued to be poor for Venstre. Before the 1985 elections, the party announced for the first, and so far only, time that they would support a Labour Party government. At the following election they lost their two remaining seats, and were without representation in the Norwegian Parliament for the first time. In 1988, Venstre was re-united with the splinter party from 1972, now calling itself the Liberal People's Party, but at the elections of 1989, the re-united party again failed to win parliamentary seats. In 1993 the party again failed to achieve the 4% threshold which would make them eligible for the leveling seats in parliament, but Lars Sponheim was elected directly from Hordaland county. (Before the election, Sponheim had made the wager that he would walk across the mountains from his home in Ulvik to the parliament in capital city Oslo if elected—a wager he delivered on, to much good-humoured interest from the press.) In 1997, Venstre passed the 4% threshold, increasing their
