Waldemar Żurek submitted the request to European Parliament President Roberta Metsola on Thursday and announced it the following day.
It is the fifth attempt to strip Braun of parliamentary immunity in connection with criminal investigations.
"Immunity is not intended to protect Auschwitz deniers," Żurek wrote on X. "Such statements have nothing to do with performing the duties of a member of the European Parliament. This is a crime prosecuted by the state."
The latest case concerns remarks Braun made during a livestream on August 25, shortly after prosecutors in the southern Polish city of Kraków questioned him over earlier statements denying Nazi atrocities at the Auschwitz-Birkenau concentration and extermination camp.
According to the National Public Prosecutor’s Office, Braun again publicly denied that Nazi Germany had committed genocide by murdering prisoners, predominantly Jews, in gas chambers at Auschwitz between 1941 and 1944.
Braun, leader of the far-right Confederation of the Polish Crown, had been questioned that day over similar statements made during a radio interview and podcast appearances in July last year.
He denied wrongdoing but did not dispute having made those remarks.
Prosecutors opened a fresh investigation following his August livestream. They say the evidence supports a reasonable suspicion that Braun violated Article 55 of the law governing Poland’s Institute of National Remembrance (IPN), which criminalizes publicly denying Nazi and communist crimes contrary to established facts.
The offense carries a maximum prison sentence of three years.
Prosecutors argue that Braun’s statements were unrelated to his parliamentary duties and therefore should not be protected by his position as a member of the European Parliament.
Speaking later at the justice ministry in Warsaw, Żurek said prosecutors would continue to pursue allegations against Braun and could seek his detention if he refused to cooperate.
"I think Braun’s impunity is coming to an end before our eyes," he said.
The European Parliament has previously lifted Braun’s immunity in several cases.
Two requests were approved in March, covering allegations including Holocaust denial, theft of Ukrainian and European Union flags, and damage to an exhibition about the LGBT+ community in Poland’s parliament.
Another case concerns an April 2025 confrontation at a hospital in Oleśnica, southwestern Poland, where Braun allegedly detained and assaulted a doctor.
Braun is also on trial in Warsaw over a December 2023 incident in which he used a fire extinguisher to put out Hanukkah candles during a Jewish religious ceremony in the Polish parliament. The European Parliament lifted his immunity in that case in May last year.
