A spokesman for the Auschwitz-Birkenau State Museum said Irving can visit as an individual, the Warsaw Business Journal reported. Irving, who is leading a group on a tour of Holocaust sites in Poland this week,
will be "closely monitored" at Auschwitz, Bartosz Bartyzel said.
Irving's itinerary reportedly includes Treblinka, the most notorious Nazi death camp. He has said Treblinka remains "genuine" and Auschwitz has been converted to a "Disney-style tourist attraction."
Irving does not deny that thousands or even millions of Jews were killed during World War II. But he denies Jews were killed systematically on the orders of Adolf Hitler.
"I am baffled by the reaction I've had in Poland because they should be very grateful that I am here," he told The Daily Telegraph. "Here I am lecturing to the revisionists and setting the record straight. I am saying to those who believe that not a hair was harmed on the head of the Jewish community that you couldn't be more wrong."
