The Charity Commission has closed an 18-month regulatory case review into JNF UK which was instigated following reaction to claims by the charity’s chairman Samuel Hayek that Muslim immigration posed a threat to British Jews.

In a statement today, the watchdog said that the compliance case “has now concluded.”

During the case, it added, “regulatory advice and guidance relating to social media usage and trustee conduct was issued to the trustees, and we’re satisfied that this has now been acted upon.”

The case had been opened “due to concerns regarding the conduct of one of the charity’s trustees, as well as the conduct of a now former trustee,” it had previously said.

Mr Hayek said, "We are delighted that our engagement with the Charity Commission has yielded a constructive conclusion, and the case is now closed.

”This outcome reflects our dedication to upholding the highest standards of governance and accountability."

The charity, which operates the KKL voucher scheme as well as raising funds for Israel, said it had worked closely with the commission over the past months and had been open in addressing any concerns or queries raised by the commission.
