Read this: During the first four days of the war, the general population of the Arab world believed Arab radio station fabrications of imminent Arab victory. On 9 June, Nasser appeared on television to inform Egypt's citizens of their country's defeat. He announced his resignation on television later that day, and ceded all presidential powers to his then-Vice President Zakaria Mohieddin, who had no prior information of this decision and refused to accept the post. Hundreds of thousands of sympathizers poured into the streets in mass demonstrations throughout Egypt and across the Arab world rejecting his resignation, chanting, "We are your soldiers, Gamal!" Nasser retracted his decision the next day.
