Prime Minister David Cameron has said that a "rapid and credible" transition to democracy in Egypt "needs to start now".
Pressure is mounting on beleaguered President Hosni Mubarak to end his 30-year rule immediately rather than wait until September elections.
At prime minister's questions on 2 February 2011, Mr Cameron said: "We should be clear: we stand with those, in this country, who want freedom, who want democracy and rights the world over.
"That should always be our view.
"You cannot watch the scenes in Cairo without finding it incredibly moving about people wanting to have those aspirations in Egypt as we have them in our country."
Labour leader Ed Miliband said: "Far from indicating support for extremism the people on the streets of Egypt are actually demanding some very basic things: jobs, freedom of speech and the right to choose by whom they are governed."
He said democracy represented the "best route to stability" in Egypt.
