A 105-year-old Dutch entertainer has lost his libel lawsuit over claims that he sang for Nazi guards at the Dachau concentration camp during World War II.

Johannes Heesters had been seeking a retraction from German author Volker Kuehn who made the claims.

But a German judge said that although this could no longer be proven, there was enough evidence to suggest that Mr Heesters appeared on stage at the camp.

Mr Heesters does admit visiting Dachau, and that he performed for Adolf Hitler.

But he insists that he never espoused Nazi politics.
