The Supreme Guide of Egypt's Muslim Brotherhood Mohamed Badie urged on Saturday all political forces to maintain calm and prioritize the interest of the nation.

In a press conference at the Brotherhood's headquarters, Badie called Egypt's opposition forces for dialogue and reconciliation as Egypt's unity is at stake.

Badie described the current scene as a political competition where the last word belongs to the people.

Political turmoil erupted when Mursi issued a constitutional decree on November 22 shielding his decisions from judicial challenges and escalated as he called for a December 15 referendum on a draft constitution written by an Islamist-dominated assembly.

"Political competition knows no crime and no murder, in such a case we should resort to the ballot boxes.. This is the mechanism of democracy", said the spiritual leader of the brotherhood, to which Egypt's president belongs.

Badie stressed that violence is not systematic in the Brotherhood, saying "We do not accept attacks on anyone. We only respond to aggression, you can be angry with the Muslim Brotherhood, but do not harm the nation" pointing out that the scuffles around the presidential palace resulted in eight martyrs and 1493 injuries who belong to the Brotherhood.

He pointed that funds are behind this strife which only serve the interests of Egypt's enemies and that what is happening now aims at weakening Egypt.

Badie denounced the claim that "The Supreme Guide rules Egypt", "How can I rule Egypt when I cannot even protect my own office", he said in reference to the attacks on the Brotherhood's headquarters.

"If the President decides to freeze the constitutional decree and postpone the referendum, we will study the situation and offer our opinion, but if everyone agrees we will not oppose it", Badie said on the position of the Brotherhood.

At the end of his speech, he called on Egyptians to present a perfect picture to the whole world of Egyptian democracy.
