Brotherhood leader Mohamed Badie said the group would use peaceful means of dissent against a Parliament that he said did not reflect the real strength of Egypt’s opposition or the will of voters. “Absent from Parliament ... the opposition will take to the streets,” Badie told Reuters. He said the movement would coordinate with other opposition groups in protests that would be “legal, constitutional and en masse.”

President Hosni Mubarak’s ruling National Democratic Party (NDP) won 420 of the 508 seats contested in the elections on Nov. 28 and Dec. 5. The Brotherhood held 86 seats in the previous parliament, giving it a platform to attack official policy. It pulled out of the elections after winning no seats in the first round. Officials said the vote was fair.

Rights groups and opposition parties said the result was secured using ballot stuffing, intimidation and dirty tricks.
