Holocaust denier and self-styled historian David Irving is leading tours of concentration camps, the Daily Mail reports Monday - at the hefty price of £2,000 ($3072) per person. 

In September, he is due to take a group of "international guests" to Latvia and Poland to visit four concentration camps, as well as one of Hitler's fortresses. The tour begins and ends in Warsaw, and will stop at Treblinka, Sobibor, Belzec and Majdanek.

Irving, 77, is known as one of the world's most vocal and prominent Holocaust deniers, after he sued Penguin Books and American scholar Deborah Lipstadt for libel in 2000 over the term - bringing his revisionist views to life. 

Among other beliefs, Irving insists that Nazi dictator Adolf Hitler did not know about the Holocaust and has played down the Holocaust's magnitude and severity. 

Irving encourages travelers to "make up your own minds" about the Holocaust, according to the Mail

"Forget the phoney [sic] allures, mass-tourism and "reconstructions" of modern-day Auschwitz - the erstwhile slave-labour [sic] camp turned into a tourist attraction, complete with hot-dog vendors and souvenir stands!," the ad reads. 

Multiple groups have already protested the tours, including the Campaign Against Anti-Semitism, the Never Again Association, and the Anti-Defamation League (ADL).
