At one point he spotted pro-Israel counter-demonstrators carrying Israeli flags.
He ordered the march to halt, insisting it would not move on until the “Zionist flag” was removed. He said: “We are fed up of the Zionists. We are fed up of their rabbis. We are fed of their synagogues. We are fed up of their supporters.”
Screaming into the microphone, Mr Ali guided the crowd in a chant of: “Judaism – yes. Zionism – no. The state of Israel must go.”
It was just as the march was about to set off that Mr Ali walked towards a small group of pro-Israeli demonstrators and began singing: “Bye, bye Zionists.”
He then made his remarks linking the Grenfell Tower tragedy to Zionism, adding: “These people do not know what justice is because it’s their supporters who are supporting the Tory Party, that’s who they are. Zionists who give money to the Tory Party to kill people in high rise blocks.“
Mr Ali turned to the large police presence and said: “I am requesting that the police watch those trouble-makers over there. They will try to incite. That’s what they are good at causing violence. Do not react to the killers of British soldiers.”
He also repeatedly drew attention to the presence of a handful of members of the Jewish anti-Israel Neturei Karta group, praising as being “true” Jews.
He added: “Because these rabbis don’t kill people, because these rabbis don’t murder people, they are told they are traitors. Because Zionism is a fascist, evil ideology. It is an evil ideology to its core – that’s what Zionism is. That is why they killed British soldiers in order to get their country.”
During the march Mr Ali also claimed “Zionists” were supporters of Isis.
He said: ”Isis are being treated in their hospitals. Isis are being supported in the occupied Golan. Everyone knows that Zionist Israel and Isis are the same. They are brothers in arms.“
The IHRC, which is based in London, has been given charitable status and states that its mission is to "work with different organisations from Muslim and non-Muslim backgrounds, to campaign for justice for all peoples regardless of their racial, confessional or political background."
The group has repeatedly called for the repeal of much UK terror legislation – including the government’s Prevent strategy.
The Community Security Trust yesterday condemned Mr Ali’s comments linking Zionism to the Grenfell Towers fire as “grotesque.”
Lord Polak CBE, Conservative Friends Of Israel’s Honorary President wrote to Home Secretary Amber Rudd to express concern over the Hezbollah flag at Sunday’s march and called on the Metropolitan Police to charge those found in “direct contravention” of Section 13 of the Terrorism Act (2000).
The UK currently proscribes Hezbollah’s so-called ‘military wing’, while the United States, Canada, the Netherlands, the Arab League, the Gulf Cooperation Council, and Israel proscribe the terrorist organisation in its entirety.
The Metropolitan Police and the Home Office have been asked for comment.
When the JC attempted to contact Mr Ali at the IHRC a spokesman confirmed he worked there and that he had been on the microphone at Sunday’s Al Quds Day event.
