How Egypt's historic day unfolded
Hosni Mubarak has stepped down as president of Egypt, after weeks of protest in Cairo and other cities
The news was greeted with a huge outburst of joy and celebration by thousands in Cairo's Tahrir Square - the heart of the demonstrations.
Mr Mubarak ruled for 30 years, suppressing dissent and protest, and jailing opponents.
