Nigel Farage has been accused of using antisemitic "code words" while appearing on the talkshow of American extremist conspiracy theorist Alex Jones.
Mr Farage appeared at least six times with Mr Jones - whose claims include that the Sandy Hook shooting is fake - and the pair used phrases and themes associated with the conspiracy theory that Jewish financiers are behind a plot to replace nation states with a global government.
During the appearances, between 2009 and last year, the former UKIP leader was found by The Guardian to have used the word “Globalists” and the phrase "New World Order", as well as suggesting members of the annual Bilderberg conference were plotting global domination.
As recently as April 2018, Mr Farage, who is now leading the Brexit Party in this month’s European elections, told Mr Jones the EU was “the prototype for the new world order”.
He also claimed “globalists have wanted to have some form of conflict with Russia as an argument for us all to surrender our national sovereignty and give it up to a higher global level”.
Antisemitism watchdog the Community Security Trust said Mr Farage's language were "familiar code words for antisemitic conspiracy theories".
A CST spokesperson called Mr Jones “a notorious conspiracy theorist who should be beyond the pale for any mainstream politician”.
“Furthermore, for Jones’s conspiracy-minded audience, Farage’s references to ‘globalists’ and ‘new world order’ will be taken as familiar code words for antisemitic conspiracy theories,” they added.
A spokesman for the Board of Deputies said: “It is vital that our politicians distance themselves from conspiracy theories and conspiracy theorists, including those who trade in antisemitic tropes.
"We would call on Nigel Farage to repudiate these ideas and to commit not to dignify oddball nasties like Alex Jones with his presence again.”
Asked at Tuesday’s Brexit Party press conference about his appearances on Mr Jones’s Infowars how, Mr Farage said: "I've done a huge amount of global media, including Chinese state media.
"As far as the Infowars site is concerned I’ve done it every couple of years. I know Jones is accused of conspiracy theories & there may be some truth of that. I have never been a conspiracy theorist.”
On Sunday, it emerged two senior members of Mr Farage’s Brexit Party were still directors – despite supposedly resigning after offensive social media messages were exposed.
The Guardian reported ex-party leader Catherine Blaiklock, who resigned after calling Islam "incompatible with liberal democracy", and Michael McGough, who resigned after saying, among other things, that Ed and David Miliband and Peter Mandelson had “shallow UK roots”, were still listed as directors.
Ms Blaiklock also retweeted far-right messages, including a reference to "white genocie" by a former BNP activist.
