Prince Harry, in the midst of a row over wearing Nazi fancy dress, should join other young people to hear about what happened in the Holocaust, Auschwitz survivor Susan Pollack says.

Young people generally show good awareness of what happened, she says, and she invited the prince to join one of her talks about her experiences which she gives to school groups, students and Holocaust centre visitors. "I'd like him to come and listen to me once. I would welcome him to participate in one of the talks," says Mrs Pollack, 74. Harry's choice to wear a Nazi outfit to a fancy-dress party is, she says, no laughing matter. "You can't laugh. There's nothing to joke about," she says. "I wish there was." "He is 20. My gosh, students of 14 know about it. I am absolutely aghast. "Ignorance is no longer acceptable about the Nazis. If [people] don't know what Nazis have done, they should drop their heads and look down at the ground." Family's fate:  In 1943, when she was 13, Mrs Pollack and her family were rounded up in their village of Felsogod, Hungary. As far as she knows, her father was killed by the fascists. Her mother was gassed when they arrived at Auschwitz in May 1944. Her elder brother Laszlo survived, despite his ordeal on slave labour duty - he moved bodies "from the gas chambers to the oven". He never recovered later in life from what he had experienced in that time. Susan also survived Auschwitz, selection at the hands of Doctor Josef Mengele, slave labour, and a death march to Belsen before liberation. She has been married to Abraham, also a holocaust survivor, for more than 50 years and they have three daughters. She has given the talks for the past 15 years, she says, "because I was there, I speak for those who can't, who died". "We are not going to be around very long so I've got to say what I can." Her testimony, she says, tells people the dangers of a "dark and evil side of humanity" and the need to live in a free, equal society with human rights.
