Egypt's army spokesman denied late on Saturday rumors that Defense Minister Abdel Fattah al-Sisi has stepped down from his post as army chief in preparation for presidential election.
Sisi, whose popularity rose sharply after he ousted Islamist President Mohamed Mursi in July, has not commented on whether he intends to run.
The army warned the Egyptian media from spreading controversial rumors that could cause confusion that may threaten national security at this critical time.
Many Egyptians, who view Sisi as their rescuer from Islamic fascism, are expected to vote for him if he did run in this year's presidential election - especially as the country undergoes what the government describes as a "war on terrorism".
When Egypt's army deposed the Mursi administration following mass demonstrations, it announced a roadmap that included suspending a constitution written last year by an Islamist-led assembly and holding early presidential and parliamentary elections.
A 50-member assembly, formed in September, finished writing a new constitution last month which Egyptians will vote on in a referendum on January 14.
