Media watchdog Ofcom is expected to rule within the next two months on a complaint about a documentary which uncovered Nazi-uniform-wearing war-games enthusiasts.
Weekend Nazis was broadcast on BBC1 in August 2007 and focused on the War and Peace Show in Kent.
It showed presenter John Sweeney meeting participants from the Second Battle Group (SBG) re-enactment organisation, many of whom were dressed in Nazi uniforms.A swastika was shown on invitations to Nick Beardshaw's wedding, at which he allegedly wore a Nazi uniform.
But Mr Beardshaw - who had agreed to be in the programme and denies being a Nazi-sympathiser - complained to the regulator about a breach of privacy after seeing the title and footage.
An Ofcom spokeswoman said the investigation into fairness in the show is yet to be completed.
Documentary makers October Films and the BBC declined to comment.
