Donald Tusk

Donald Franciszek Tusk (born 22 April 1957) is a Polish politician and historian who has served as the prime minister of Poland since 2023, previously holding the office from 2007 to 2014. Tusk was President of the European Council from 2014 to 2019 and led the European People's Party from 2019 to 2022. He co-founded the Civic Platform (PO), one of the dominant Polish political parties, and was its longtime leader – from 2003 to 2014 and again from 2021 to 2025 – before it merged into the Civic Coalition (KO) party. He is the longest-serving prime minister of the Third Polish Republic.

Tusk has been officially involved in politics since 1989, having co-founded multiple political parties, such as the free market–oriented Liberal Democratic Congress party (KLD). He first entered the Sejm in 1991 but lost his seat in 1993. In 1994, the KLD merged with the Democratic Union to form the Freedom Union. In 1997, Tusk was elected to the Senate and became its deputy marshal. In 2001, he co-founded another centre-right liberal conservative party, the PO, and was again elected to the Sejm, becoming its deputy marshal. Tusk stood unsuccessfully for President of Poland in the 2005 election and would also suffer defeat in the 2005 Polish parliamentary election.
