The Jewish community has been encouraged to come up with solutions to stop Nazi impersonators from infiltrating Second World War re-enactment events across the UK.
The general manager of the East Lancashire Railway, Andy Coward, said this week that he welcomed ideas on how to stop the imitators.
The heritage railway came under pressure from Manchester's Jewish community to ban dozens of actors who were spotted wearing Nazi insignia at its May event. It sparked angry complaints from local Jewish politicians.
Policies printed in event guides ban official re-enactment companies from using swastikas, SS insignia or black Nazi uniforms. But Mr Coward said a new strategy will be required to police unofficial Nazi impersonators who attend the public events and break the rules.
