In the most recent parliamentary elections of 2019, five parties gained seats at Riigikogu. The head of the Centre Party, Jüri Ratas, formed the government together with Conservative People's Party and Isamaa, while Reform Party and Social Democratic Party became the opposition. In January 2021 Ratas resigned as prime minister in the wake of a corruption scandal, and Reform Party leader Kaja Kallas became Estonia's first female prime minister, making Estonia the only country in the world to currently be led by both a female President and Prime Minister. The new government was a two-party coalition between country's two biggest political parties Reform Party and Centre Party.
