The Guardian's live-blog is up and running with Matthew Weaver at the helm:
8.34am: "A lot of protesters are hoping and believing that this could be the final hours of the Mubarak regime," Jack Shenker reports from Cairo. The million-person march to the presidential palace will take the protests to a new level, it is hoped, he says. The regime's tactics to prevent people taking part, won't work, Jack predicts. "Tens of thousands of people have defied a strict night curfew after night," Jack says. "Right now in Tahrir, there is a huge presence, far bigger than it has been at this time. There are tens of thousands certainly. Thousands from different directions are streaming towards the square."
