Riot police have been trying to clear anti-government demonstrators from Tahrir Square in the Egyptian capital Cairo overnight.
The police could be seen setting fire to makeshift tents in the square and beating up at least one protester.
Demonstrations are expected today marking the second anniversary of the uprising that toppled President Hosni Mubarak.
A student asked the Prime Minister "what is your next step in Arab Spring countries?"
He replied: "I am a supporter of the Arab Spring". He said that all countries should be free to follow their own paths, but that he wanted to encourage the "building blocks of democracy" such as rule of law, women's rights and a free press.
Newly-elected MP George Galloway quit a Channel Four News interview after objecting to presenter Cathy Newman's questions when he likened his win to the Arab Spring. "We saw a Bradford Spring, a kind of peaceful, democratic uprising. That's what I think it was, you evidently don't," he told Newman.
