Egyptian opposition figure Ayman Nour said Thursday he would not begin negotiations with the government until President Hosny Mubarak steps down, DPA reported.
"The only solution is for Mubarak to leave power," said Nour, a former presidential candidate, who spent four years in jail after vying for the country's top job.
"I will not take part in these talks," Nour told the German Press Agency dpa. He was referring to negotiating with Vice President Omar Suleiman.
His stance was in line with that also taken by the Muslim Brotherhood and Nobel Peace Prize laureate Mohamed ElBaradei, who say they would talk with Suleiman, but only once his boss resigned.
The vice president has said he would negotiate with anti- government protesters but only once they went home. While his office said a line of communication was opened with some opposition movements, it gave no specifics.
Nour meanwhile called for international intervention to end violence in Cairo.
"I call on the rational world to interfere to protect the protesters, and I mean the United Nations," said Nour.
