Swedish Queen Silvia Thursday said a probe into her father's Nazi past has been concluded and she had "no reason" to reassess her view of him.

In a six-minute video posted on the palace web site, the German-born queen said the two-year investigation into her late father's past had been "emotionally trying."

The study was commissioned by the queen and the Sommerlath family after a 2010 television documentary alleged that her father, Walter Sommarlath, had taken over a company owned by a Jewish businessman as part of the Nazi regime's so-called Aryanization program in which Jewish property and businesses were expropriated.

The palace Thursday published more documents and a 72-page report titled The Forgotten Documents, which said Sommerlath, who died in 1990, had conducted a "swap" that allowed Jewish businessman Efim Wechsler to emigrate from Nazi Germany.

Erik Norberg, former head of the Swedish national archives, conducted the research on behalf of the queen, drawing on archives in Brazil and Germany. A first report was published in August 2011.

Norberg concluded that the queen's father swapped his coffee farm in Brazil for a German-based business owned by Wechsler, allowing the stateless businessman to emigrate from Germany.

The queen, 68, said the delay in seeking information about her father's past was "perhaps due to fear, and that fear is something I share with many of my generation who were born during or after the war."

Her parents never discussed the war with her or her brothers, she said.

The report has "filled in a knowledge gap for me," she said, adding that "the investigation was now completed as far as possible."

The queen said she was "deeply affected" on learning that her father had joined the Nazi party in 1934, the year after Adolf Hitler became chancellor.

In a preface to the report and the video clip she strongly rejected Nazism and the atrocities committed against the Jewish people.

Johan Asard, former head of Tv4's investigative program Kalla Fakta that 2010 broadcast the documentary, said "nothing really new" appeared to have emerged in the new documents published by the palace.
