The German government has been asked to open an investigation into the workings of the far-right LaRouche group.
Jeremiah Duggan was found dead on a highway in Wiesbaden, Germany, in 2003, while attending a LaRouche youth event.
The student’s parents have presented the German Embassy in London with a dossier detailing the group’s antisemitic links.
This week, Jon Benjamin, chief executive of the Board of Deputies, joined Erica and Hugo Duggan at a meeting at the embassy with Germany’s deputy ambassador, Dr Eckard Lubkemier.
