The Charity Commission last week announced an inquiry into the foundation and froze its bank account following the action taken by the UK government against Dr Kantor.
The inquiry would “determine whether the charity can continue to operate and is viable following sanctions being imposed on the founder”, the commission said.
Dr Kantor, who is chief executive of the Acron Group – one of the world’s largest producers and distributors of fertiliser – has stepped back from the presidency of the European Jewish Congress following the UK sanctions.
The EJC said it was “shocked and appalled” by the government’s decision, which it called “misguided”. Six years ago, Dr Kantor headed an EJC delegation to see Mr Putin, who reportedly suggested that Jews fleeing antisemitism could take refuge in Russia.
In its statement, King Solomon said: “The ethos and day-to-day running of the school remains unchanged, and the school continues to put students at the centre of everything we do to help them develop in line with our values of learning, community and charity, which underpin all our work.”
