A stall selling Nazi memorabilia on Remembrance Sunday was removed after a complaint it was offensive.
An Arms & Armour Militaria Fair, which sells military collectables from the Second World War, was held at Stantonbury Arts and Leisure Centre on Sunday.
The stand displayed helmets and uniforms on a table draped with a Nazi flag on the day millions were commemorating 70 years since the end of the Second World War.
Phil O’Neil, director of Arts and Leisure at Stantonbury, said he acted immediately to remove the stall when a complaint was made by a leisure centre visitor.
Speaking to the Citizen, he said: “We accept responsibility for the oversight and would like to assure everyone we will be taking all necessary steps to make sure nothing like this happens again.
“We want to make clear we do not condone the display. As soon as we were made aware, it was removed.
“We apologise unreservedly for any offence caused.”
Arms & Armour describe themselves as Britain’s premier militaria fairs organiser, hosting events across the UK since 1969 and hiring the venue at Stantonbury for the past four years.
Mr O’Neil has launched a full investigation, with plans to tighten up regulations to make clear what is “acceptable” for such events.
Arms & Armour were unavailable for comment.
