The hardline activist at the forefront of the "Jewish Division" of the extreme right-wing English Defence League has announced that she does not wish to be a part of it any longer because of Nazi elements within it.
Roberta Moore, who has led the Jewish Division since it was launched more than a year ago, was accused earlier this month of being a divisive figure in the EDL.
Ms Moore had attempted to co-ordinate her efforts with those of the far-right American Jewish Task Force, whose leader Victor Vancier has been imprisoned for terrorism offences. The move, in February, was heavily criticised by the EDL leadership.
In a statement which she posted on Facebook, the Brazilian-born Ms Moore said she had been offered work on "an international level" elsewhere and so had decided to step down from the Jewish Division.
Although she described the EDL as "doing a fantastic job" she said the party had been hijacked by elements who wanted to use it "for their own Nazi purposes".
Ms Moore said she still supported the EDL leaders and "all the genuine patriots out there who struggle to get their voices heard" but added that she no longer wished to be a part of it.
"I sincerely hope that the leaders will get the strength to squash the Nazis within," she said.
"They will destroy this movement if allowed to remain."
Mark Gardner, from the Community Security Trust, said: "This latest development shows, yet again, why Jews should not be involved in such circles."
