Prince Charles has been criticised for comments he made in a letter more than 30 years ago where he suggested an influx of ‘foreign Jews’  was partly to blame for trouble in the Middle East.

The Mail on Sunday today revealed a letter, which was written by the heir to the throne, to explorer Laurens van der Post. It read:Dear Laurens, Am on my way to Cyprus and Italy having passed through Suez Canal. Lovely having three days at sea. This tour has been fascinating and have learned a lot about Middle East and Arab outlook. Tried to read a bit of Koran on way out and it gave me some insight into the way they think and operate. Don’t think they could understand us by reading the Bible though. Much to admire some aspects of Islam – especially accent on hospitality and accessibility of rulers.

“Also begin to understand their point of view about Israel. Never realised they see it as a US colony. I now appreciate that Arabs and Jews were all a Semitic people originally and it is the influx of foreign, European Jews (especially from Poland they say) which has helped to cause great problems.

“I know there are so many complex issues, but how can there ever be an end to terrorism unless the causes are eliminated? Surely some US president has to have the courage to stand up and take on the Jewish lobby in the US? I must be naïve, I suppose! Charles.”

Gideon Falter, Chairman of Campaign Against Antisemitism, said: “This letter is disturbing. It appears that our future king believed in 1986 that the “influx” of Holocaust survivors to Israel were not “Semitic”, “cause great problems” including terrorism, and should be “eliminated”, presumably through their removal. The letter also appears to endorse the view that Israel is not simply the result of Jewish self-determination in the historic Jewish homeland, but the result of bullying by an all-powerful “Jewish lobby” which holds US presidents in its clutches. We view these comments as unmistakably antisemitic.

“However, since the letter was written, the Prince of Wales appears to have warmed to the Jewish community and we note his friendship with the former Chief Rabbi, Lord Sacks, as well as his attendance at the inauguration of the present Chief Rabbi, Ephraim Mirvis.

“In order to reassure the worldwide Jewish community, including Jews living in Israel, that the heir to the throne has changed his views, these historic remarks must urgently be repudiated by Prince Charles.”

A statement from a Clarence House spokesperson said the opinions were “not The Prince’s own views”, but instead reflected the opinions of those he met on his trip. 

It said: “The letter clearly states that these were not The Prince’s own views about Arab-Israeli issues but represented the opinions of some of those he met during his visit which he was keen to interrogate.

“He was sharing the arguments in private correspondence with a long standing friend in an attempt to improve his understanding of what he has always recognised is a deeply complex issue to which he was coming early on in his own analysis in 1986.

“Over the years, The Prince has continued his study of the complex and difficult themes he referenced here. He has built a proven track record of support for both Jewish and Arab communities around the world and has a long history of promoting interfaith dialogue and cultural understanding.”
