Mahmoud Ezzat, the Muslim Brotherhood's deputy supreme guide, on Sunday denied the group was interfering in the formation of President Mohamed Morsi's new cabinet.
He insisted the Brotherhood was only offering general advice to the president, who was a long-term member of the group.
He also denied the group's guidance bureau had discussed potential ministers during its weekly meeting on Saturday.
However, the Brotherhood's political wing, the Freedom and Justice Party (FJP), had the right to present a list of preferred ministers for the new cabinet just like any other party, Ezzat added.
It was reported by Al-Shorouk newspaper on Friday that the group's second deputy supreme guide, Khairat El-Shater – who is believed to be the group's mastermind – would be the FJP's candidate to become deputy prime minister.
President Morsi, who was the FJP's election candidate, is expected to form a new government after the Islamic holy month of Ramadan, which ends on 18 August.
Morsi resigned from his position in the Brotherhood after his presidential election victory.
