Sen was suspended from Ukip on May 1st after a series of apparently Anti-Semitic tweets. It was too late for him to be removed from the ballot, but the party explained he would not have been allowed to sit in the House of Commons as a Ukip MP were he elected.
In a speech to far-right group the London Forum, he claimed he had been suspended after a complaint was made by a prominent Jewish member of Ukip.
He said: “I might be naive. I found Ukip organically, I thought it was a great organisation. I don’t know if it’s been hijacked, or I was naive from the beginning and it was already in the pockets of Jewish special interest groups. But I’m afraid that at this point it has been taken over.”
He adds “I have a bad feeling that something stinks.”
A Ukip spokesman said: “Jack Sen was suspended when we became aware of his views, and has since left the party.”
A video of the speech emerged just the day after Sen told Channel 4 News he was a “national socialist” and praised Oswald Mosley and Enoch Powell.
He said: “If national socialist means that I love my country, believe in a strong national identity, will fight to preserve our culture and want a strong society, safety net for the poor, national healthcare etc. then certainly I see myself as a national socialist.”
National Socialism is the full name of Hitler’s Nazi party.
In his speech he said: “”I know the way I think and it might be Anti-Semitic, I’m not sure.”
When the London Forum member who introduced Mr Sen made reference to his suspension for Anti-Semitism, it was met with applause and cheers from the audience.
Sen took a question after his speech from an audience member who claimed to have been “expelled from Ukip” – but said he still worked for the party “incognito.”
A Ukip spokesperson said they found it unbelievable nor could they identify the audience member, but would look into it.
Sen gave his speech to the London Forum, a group that describes itself as a “non-party aligned conference group for nationalists,identitarians, thinkers and commentators from across the Right”.
