Jarosław Kaczyński

Jarosław Aleksander Kaczyński (born 18 June 1949) is a Polish politician. He co-founded the Law and Justice (PiS) party in 2001 with his twin brother, Lech Kaczyński, and has served as its leader since 2003. He served as Prime Minister of Poland from 2006 to 2007, and has twice held the post of Deputy Prime Minister of Poland, first from 2020 to 2022, and a second time from June to November 2023. He is considered to have been the éminence grise of Poland, when PiS formed the government in 2005–2007 and again in 2015–2023, with direct political influence over the prime ministers Kazimierz Marcinkiewicz, Beata Szydło and Mateusz Morawiecki.
