I want to know the answer to the following question:
Who was the executive head of the Zionist Organization?
All the background I'm provided with is that "That day, David Ben-Gurion, the executive head of the Zionist Organization and president of the Jewish Agency for Palestine, declared "the establishment of a Jewish state in Eretz Israel, to be known as the State of Israel," which would start to function from the termination of the mandate.". Is that enough to answer the question?
