Hosni Mubarak, the Egyptian president, has resigned from his post, handing over power to the armed forces.
Omar Suleiman, the vice-president, announced in a televised address that the president was "waiving" his office, and had handed over authority to the Supreme Council of the armed forces.
Suleiman's short statement was received with a roar of approval and by celebratory chanting and flag-waving from a crowd of hundreds of thousands in Cairo's Tahrir Square, as well by pro-democracy campaigners who attended protests across the country on Friday.
The crowd in Tahrir chanted "We have brought down the regime", while many were seen crying, cheering and embracing one another.
