An Islamist activist has claimed the Grenfell Tower victims “were murdered” by Zionists who fund the Conservative party in an astonishing outburst now being investigated by police.

Nazim Ali, a director of the Islamic Human Rights Commission (IHRC), is accused of exploiting the tragedy during an anti-Israel demonstration in the days after the fire.

The Metropolitan Police said it was now investigating allegations of anti-Semitic comments made during the protest.

Mr Ali, who is managing partner of a private health clinic in west London which charges patients up to £150 for a GP consultation, told the rally on June 18: “As we know in Grenfell, many innocents were murdered by Theresa May’s cronies, many of which are supporters of Zionist ideology.”

In video footage posted online, Mr Ali goes on: “Let us not forget that some of the biggest corporations who were supporting the Conservative Party are Zionists. They are responsible for the murder of the people in Grenfell, in those towers in Grenfell, the Zionist supporters of the Tory Party.”

In another heated outburst, he says: “It is the Zionists who give money to the Tory party, to kill people in high rise blocks.... Careful, careful, careful of those rabbis who belong to the Board of Deputies, who have got blood on their hands.”
