A national newspaper has claimed that Lincolnshire UKIP councillor Victoria Ayling was once a member of the far-Right National Front.
The Mail on Sunday says that Victoria's mother, a family friend and her ex-husband have spoken to them about her political activities with the extremist organisation in the 1970s.
Brenda Brooks, who is 81, apparently told the newspaper that her East Lindsey District Council member daughter began going to NF meetings above a pub in Croydon, south London, in 1977.
Yet Mrs Ayling has claimed that her presence at the group's gatherings was merely part of an academic research project.
The former Conservative's mother is also said to have claimed that Victoria attended rallies, marches, and campaign meetings for one of the far-Right party's election candidates in 1979.
The new revelations follow the Mail on Sunday's recent publication of a video from 2008 which shows Ayling airing controversial views about immigrants. She claimed the comments had been taken out of context.
Brenda Brooks allegedly described Victoria's NF involvement as being a 'phase'.
And a former friend claims they were active in the NF together, and is said to have referred to her as 'card-carrying'.
The Mail also claim that her ex-husband Rob Ayling has also come forward to allege that he helped to cover up her past activities when they were married.
His former wife has defended herself, according to the newspaper, by stating that she attended meetings as part of a research thesis while studying law at Southampton University and that she was not a paid-up NF member.
Mr Ayling apparently said this version of events was concocted by the pair of them as a cover story when she stood as a Conservative party candidate in 1999.
He is then said to have claimed his ex-wife was active in far-Right politics while still at school, and that such a thesis would have been irrelevant to a law degree.
The Mail also adds that Brenda Brooks refuted the 'research' excuse and said Victoria had never mentioned such a project while a student.
Ayling, 54, has only been a UKIP councillor since May.
The newspaper also revealed that they believed Lincolnshire Police had interviewed the former couple over an alleged domestic dispute at their home soon before their split in 2012.
Mrs Ayling was accused during the incident of calling her spouse a 'bad tranny' in reference to his alleged cross-dressing activities.
No charges have been brought.
