Brunhilde Pomsel, the former secretary of Nazi propaganda minister Joseph Goebbels, has died aged 106.

Pomsel lived most of her life in relative obscurity until a German newspaper published an interview with her in 2011, prompting a flurry of interest in one of the last surviving people who had access to the Nazi leadership's inner circle.

Her death was confirmed on Sunday by Christian Kroenes, a director and producer of the film, A German Life.

In the documentary, Pomsel talks about her three years working for the man responsible for spreading Adolf Hitler's ideology in newspapers and across the airwaves.

"She absolutely admitted to have been naive, proud of her work and career-driven," Mr Kroenes said.

"Of course, she didn't know at that time that she would end up at the centre of evil at some point."

Pomsel described Goebbels as a vain man, whose hate-filled public speeches were difficult to reconcile with what she said was his considerable charm when not in the spotlight.

"The only thing you can say about Goebbels is that he was an outstanding actor. He was a good actor," she said.

"No other actor could have been any better at performing the transformation from a civilised, serious person into that ranting and raving rowdy than himself."

Pomsel said she was simply a secretary and knew little of the Nazis' brutal actions during the Holocaust, according to the BBC.

Mr Kroenes said Pomsel had been lucid when he last spoke to her on her birthday on January 11.

He said she died at her Munich home on Friday (local time).

Funeral arrangements were not immediately known.
