A mother who has fought a seven-year campaign to discover why her Jewish son died after attending a conference of far-right extremists in Germany has won her right to have a second inquest into her son's death.

Two judges at the High Court yesterday decided that there was enough evidence of “foul play” to warrant a fresh inquest into how Jeremiah Duggan died on a dual carriageway in the German city of Wiesbaden in March 2003. His mother Erica believes the evidence points to her 22-year-old son being murdered and says new evidence has come to light since an initial inquest, which recorded an open verdict.

Duggan was studying at the Sorbonne in Paris at the time of his death. He had travelled to Wiesbaden to attend what he thought was an anti-Iraq war conference. It was organised by the La Rouche movement, a far-right, strongly anti-Semitic group described by UK police as “a political cult with sinister and dangerous connections”.
