Ahmed Aqeel, a spokesman for the Brotherhood's Freedom and Justice party, said establishing offices for the organization in France and other countries was essential to form a government in exile, al-Masry al-Youm reported.
Creation of a government in exile would allow the Brotherhood to sue the interim Egyptian leaders in the International Criminal Court.
In Twitter messages, Brotherhood-linked historian Mohamed Al-Gawady listed 25 members of the dissolved parliament who would take part in the exile government. Ten of the officials are in prison.
He claimed 20 countries would recognize the government-in-exile in the first week after it was formed.
Al-Gawady said by forming this government, the Muslim Brotherhood would "be prepared to take over Egypt after the coup leaves."
