The broadcasting watchdog Ofcom has partly upheld a complaint of unfairness against the programme Weekend Nazis shown on BBC1 in August last year.
It included footage of Nicholas and Michaela Beardshaw's wedding during Kent's annual "War and Peace Show", a World War Two re-enactment event, at which the couple were dressed as German army medics and some of the guests wore SS uniform.
Ofcom said the couple's privacy had not been infringed but they had not been told the nature of the programme by its makers.
