Sławomir Jerzy Mentzen (born 20 November 1986) is a Polish right-wing libertarian politician, entrepreneur, and tax advisor.

[10][11] Mentzen has also put focus on economic matters, expressing concern about the weight of taxes and the extent of welfare spending.

These issues have become central to his political agenda, resonating with voters who share similar concerns about the country's fiscal policies.

Among them were the proposals for a prison sentence for performing an abortion, the creation of “undissolvable marriages” for those who wanted them, the legalization of light corporal punishment of children by parents, and the ending of Poland’s ban on promoting nazism and using hate speech.

[18][19] Mentzen criticized the government's decision to impose a ban on Russian coal imports as part of the sanctions against Russia following its invasion of Ukraine.

He states that this move was a wrong step by the Polish authorities, particularly considering the coal shortage and high prices the country is currently facing.

Mentzen argued that the origin of the coal should not matter to consumers, emphasizing that the priority should be ensuring affordable and accessible heating options, especially for vulnerable individuals like the elderly.

[27][28][29] As of October 2023, Sławomir Mentzen's estimated net worth is approximately 49.1 million Polish złoty, consisting of various assets, including cash, cryptocurrencies, investments, real estate, and business holdings.
