 Early in his tenure at the Board of Deputies he had to respond to the controversy following the publication of photographs of Prince Harry wearing a fancy dress Nazi uniform.This episode was followed by the incident in which the then Mayor of London, Ken Livingstone, called a Jewish journalist a "German war criminal" and a "concentration camp guard", which prompted the Board of Deputies to refer the matter to the Standards Board for England, along with some two dozen other complainants.Jon Benjamin has subsequently played a leading role in issues affecting the UK Jewish community, including on the issues of faith schools, Holocaust era looted art, interfaith activity and domestic and international affairs.
