Leading German far-right figure Andreas Kalbitz admitted to participating in a 2007 commemorative rally organised in Greece by the ultra-nationalist Golden Dawn party.
News magazine Der Spiegel published a leaked report by the German embassy in Athens naming him as one of “14 neo-Nazis” who arrived from Germany for the far-right rally.
Kalbitz released a statement saying he took part out of “curiosity.” However, he denied being part of a delegation including members of Germany’s neo-Nazi NPD party.
The group reportedly unfurled a swastika flag over a balcony, which led to Greek anarchists firebombing the hotel. Kalbitz said any suggestion he was involved in the incident were “simply a lie.”
Kalbitz leads the Alternative for Germany (AfD) party in the state of Brandenburg.
The AfD has come under increased pressure to disavow apparent neo-Nazi figures among its ranks.
Kalbitz is seen as one of the more extreme figures in the party.
“Whoever surrounds themselves with neo-Nazis and marches with right-wing radicals abroad, tramples all over our democratic values,” German Finance Minister Olaf Scholz of the centre-left Social Democrats said on Twitter. “The evidence against the AfD leader in Brandenburg weighs heavy.”
Brandenburg State Premier Dietmar Woidke said he hopes that the electoral winner will not be “a party that stands for exclusion, hatred and agitation.”
