Alexander Huryn hails from a Ukrainian family but has lived in the UK since 1948. He became a naturalised British citizen in 1964 and has been married to an Englishwoman for over half a century, living in a bungalow in Fareham, Hampshire.
Huryn served as a guard at the SS-run camp at Trawniki, near Lublin, south east Poland. Historians say that thousands were murdered at the camp.
Guards from Trawniki took part in Operation Reinhard, the plan by the Nazis to exterminate Polish Jews.
Huryn's wartime past was uncovered by Dr Stephan Ankier, a Holocaust researcher who has made use of previously classified Soviet files.
Mr Huryn however has been swift to rebuff accusations of being involved in the Holocaust, claiming that his family even sheltered Jews during WW II.
“I absolutely never saw anyone get killed at the camp and I never killed anyone,” the pensioner told the local Daily Echo.
“I don't like what the Nazis did. I feel bad about what happened at Trawniki. It was terrible – but I had nothing to do with it.”
The 90 year-old, who grew up on a farm in Wola Uhruska, a village east of Lublin, claims that he had little choice but to tow the line once the Nazis arrived.
He insists he was told to. “take the job or die,” by the Nazi regime. Huryn adds that his main job was to groom horses for Nazi officers.
Through his SS past, the pensioner has also been linked to a battalion that committed atrocities against Poles.
However, at this distance of time, it is questionable whether any concrete proof as to whether he did or did not take part in crimes can be found.
Many Ukrainians living in eastern Poland during the 1930s felt that the Germans would be natural allies in creating a Ukrainian state.
However, although there was widespread jubilation when Hitler's forces pushed out the Soviets - who had occupied much of Eastern Poland since 1939 - the Germans did not create such a state. They did, however, use a considerable amount of Ukrainian manpower. (nh/pg)
