Egyptian President Mohamed Morsi scheduled the start of parliamentary elections for April 22. Members of the Coptic Christian community expressed concern over a late April start because of conflicts with Easter celebrations in Egypt.
Egyptian opposition leader Mohamed ElBaradei told the BBC he was calling for a boycott of the elections, describing it as a "sham poll."
"We need to send a message loud and clear to the people here and outside of Egypt that this is not a democracy, that we have not participated in an uprising two years ago to end up with a recycling of the (Hosni) Mubarak regime," he said.
Morsi was elected in June as a candidate from the Muslim Brotherhood's Freedom and Justice Party. His administration has faced steady criticism for not doing enough to reform the country since the 2011 revolution.
Murad Ali, a spokesman for the Freedom and Justice Party, said in a statement that there was no justification for an election boycott. Opposition leaders like ElBaredei, he said "are really worried about the world finding out the truth of their popularity -- or lack thereof -- on the ground."
