A notorious German pensioner known as the “Nazi grandma” who has been jailed several times for denying the Holocaust was sentenced to another 16 months at her latest trial on Wednesday.

As per a report, a Hamburg court convicted Ursula Haverbeck, 95, of denying the Nazi genocide on several occasions, including in 2015 during the trial of a former Nazi camp guard.

In their sentencing, the judges took into account her previous convictions and the fact she had “also used the proceedings to further disseminate her views”, a court spokeswoman told AFP.

“You’re not a Holocaust researcher, you’re a Holocaust denier,” the presiding judge said in the courtroom, adding “it’s not knowledge you’re spreading, it’s poison.”

Haverbeck repeated her remarks on the Holocaust several times at the trial.

Haverbeck was reportedly once head of a ‘far-right’ training centre shut down in 2008 for spreading Nazi propaganda.

She has previously been sentenced on several occasions to jail for denying the Nazi genocide, once declaring on television that “the Holocaust is the biggest and most sustained lie in history.”

German law makes it illegal to deny the genocide committed by Adolf Hitler’s regime. Holocaust denial and other forms of incitement to hatred carry up to five years in prison in the country.
