Career
In 1991, Zalewski was elected to the Sejm as a Democratic Union party member in the 26 Siedlce electorical district.[3] He was elected again on 25 September 2005 as part of the Law and Justice platform with 14,068 votes in the 11 Sieradz district.[11] During his term, he served as the deputy chairman of the Foreign Affairs Committee.[12][13] Despite being the party's vice president, he left Law and Justice in 2007 along with fellow member Kazimierz Ujazdowski after an argument with former Prime Minister Jarosław Kaczyński.[14][15] He joined the Civic Platform (PO) in 2009[16] and was a member of the European People's Party Group by 2012.[2][17] He was reelected to the Sejm in 2019 as a member of the PO with 12248 from the 20 Warsaw electoral district.[18]
In 2020, he criticized Vladimir Putin for "destroying historical truth".[21] In August 2021, he voted as an independent MEP against a proposal for increasing the president's salary.[22] In September, still without a party, he voted in favor of aiding Afghan refugees.[23]
2021 removal from the Civic Platform
On 14 May 2021, Zalewski and Ireneusz Raś were removed from the Sejm at the request of the Civic Coalition (KO).[12] They were summarily removed from PO and relieved of all committee responsibilities.[24][12] The ejection occurred after Zalewski and Raś signed a letter along with several senators and 49 other MEPs from PO and KO calling for a change in leadership within the coalition.[16][25][26] Both appealed their respective removal,[27] which the PO defended by criticizing Zalewski for sharing his contrary opinions with the media but refusing to speak up during diplomatic meetings during his years as a Sejm member.[28] The formal hearing has been postponed twice and is currently scheduled for 29 September 2021.[needs update][29]
