ElBaradei himself says he is willing to work with the Muslim Brotherhood, denying that they want to replicate Khomeini's Iran.

"The Muslim Brotherhood has nothing to do with the Iranian model, has nothing to do with extremism as we have seen it in Afghanistan and other places. The Muslim Brotherhood is a religiously conservative group. They are a minority in Egypt," he told CNN.

"I have been reaching out to them. We need to include them. They are part of the Egyptian society, as much as the Marxist party here," he said.

He rejected the idea that Islamic fundamentalists are set to undermine Egypt.

"This is a myth that was sold by the Mubarak regime -- that it's either us, the ruthless dictators, or... the al Qaeda types," he said.
