Cross-section of Egyptian society attend protests

Egyptian protesters are holding huge rallies in Cairo and other cities as they step up their efforts to force President Hosni Mubarak from power.

Journalists at the scene estimated that hundreds of thousands of people - men, women and children from a cross-section of Egyptian society were there, although in the absence of official estimates, there is no way of finding out the exact numbers.

George Alagiah went to meet some of the protesters.
