He was the chairman of the party KORWiN until his resignation on 15 October 2022, and from 2019 to 2023 a member of the Sejm, elected from the electoral list of Confederation Liberty and Independence.

[12] The Korwin-Mikke family, with its origins in the Kingdom of Sweden, migrated through the Electorate of Saxony to Poland, following the Great Famine of 1695–1697, alongside Augustus II the Strong, after he was elected king of the Polish-Lithuanian Commonwealth in 1697.

Korwin-Mikke is a distant relative of Hellmuth von Mücke, an officer of the Kaiserliche Marine, the navy of the German Empire, in the early 20th century and World War I.

At the time we were in Warsaw, his Union of Real Policy was housed in a former dwelling that was a literal maze of small offices, all occupied by young people actively working on spreading the libertarian gospel.

In August 1980 he supported the political strike of the Szczecin Shipyard workers, and later he was an adviser of NSZZ Rzemieślników Indywidualnych "Solidarność" (Independent Craftsmen's Union).

Notably, during his time as deputy, he was the originator of the vetting resolution of 28 May 1992 [pl], which obliged the Minister of Internal Affairs to disclose the names of all politicians who had been communist secret police agents.

[24] He frequently refers to figures such as Frédéric Bastiat, Alexis de Tocqueville, Friedrich Hayek, Milton Friedman, Margaret Thatcher and Nicolás Gómez Dávila, among others.

[31] On 18 October 2023, the head of Confederation's electoral campaign, Witold Tumanowicz, informed the Polish Press Agency that a decision had been made by the party court to "expel Janusz Korwin-Mikke from the Council of Leaders and suspend him" in the rights of a Confederation member, after Tumanowicz blamed Korwin-Mikke for the electoral defeat of the whole party.

"[32] On 29 October 2023, Sławomir Mentzen, the chairman of New Hope party, announced on social media that Janusz Korwin-Mikke will not be running on the Confederation's list in the next elections.

Mentzen added that he faced a "tragic choice" and stated: "Unfortunately, the responsibility for the political project, for future results, for ensuring that the effort of our candidates and supporters is not wasted, forces me to make this difficult decision.

"[33] New Conservatives Defunct Historical Korwin-Mikke has been described as a "perpetual political gadfly" by Politico, and as "a colorful and abrasive character" by The Guardian.

[35] In 1991 Korwin-Mikke published his guidebook for men, "Father's Vademecum", in which he wrote many pieces of advice that have been recognized as highly controversial and sexist, such as "If you cannot resolve conflict with your wife in any way, if you cannot convince her, then, unfortunately, you have to use physical force.

"[45] On 1 March 2017, Korwin-Mikke sparked controversy by stating that women were paid less than their male counterparts on average due to them being "smaller, weaker and less intelligent", during a debate in the EP regarding the gender pay gap.

[46][47] Two days later, Korwin-Mikke made further comments stating that there was a stereotype that "women have the same intellectual potential as men” and it “must be destroyed because it is not true.”[48] The situations described above, that took place in the gender pay gap debate, culminated in a court hearing.

Korwin-Mikke was one of the few voices supporting the ruling, saying on Twitter, "If they don’t scream, it shows they want it," and "This criterion has worked for 6,000 years," drawing criticism.

[54] The decision was taken after his speech about EU employment policy on the plenary session on 16 July, during which he said (in English): 'we have 20 million Europeans who are now negroes of Europe'.

[62] He objected to the Polish government's decision to bar Holocaust denier David Irving from entering Poland.

[62] In 2020, while making comments on the COVID-19 pandemic, he stated that anti-Jewish pogroms made Jews powerful via natural selection and that rabbis may have engineered this.

[66][67] On 15 April 2015, the Polish news outlet Wiadomości quoted Korwin-Mikke that the snipers that shot civilians and police officers during the Maidan protests were trained in Poland and that they acted on behalf of the CIA to provoke riots.

[70] Following the beginning of protests in Belarus, Korwin made a statement praising Belarusian president Alexander Lukashenko as a hero for his opposition to the EU.

[71] In regard to welfare, Korwin-Mikke claimed that "if someone gives money to an unemployed person, he should have his hand cut off because he is destroying the morale of the people".

[44] On 8 September 2015, Korwin-Mikke was giving a speech in EP about the European migrant crisis, during which he described immigrants unwilling to work and only interested in welfare as "human garbage".

[86] Korwin has married three times in total, most recently in 2016 to Dominika Sibiga,[note 1] who met him during an UPR meeting in 2009 and is 44 years younger than him.
