An Egyptian Muslim Brotherhood official resigned in protest against a cordial letter sent by Egypt’s President Mohammed Morsi to his Israeli counterpart, and urged Morsi to resign for his “treason” in sending it.

Ahmad Hamrawi, former secretary general of the lawyers’ association in Alexandria and a founder of Morsi’s Freedom and Justice party, left the Muslim Brotherhood following publication of the letter of credence sent by Morsi to his Israeli counterpart Shimon Peres on the occasion of the arrival of Egypt’s new ambassador to Israel, Atef Salem, on October 17.

“What Morsi said in his letter to the Zionist entity… is national and religious treason to millions of Egyptians,” wrote Hamrawi in a press statement Saturday, ending his 28-year membership in the Muslim Brotherhood.

Hamrawi called on Morsi to resign and on the leadership of the Muslim Brotherhood to denounce the letter. He told the independent Egyptian daily Al-Masry Al-Youm that the letter proved that “secret agreements and ties” exist between the Muslim Brotherhood and Israel, “far from the gaze of the [Egyptian] people and Muslim Brotherhood members.”

Deposed president Hosni Mubarak was better than the Muslim Brotherhood, Hamrawi added, according to Egyptian media, because he at least admitted his ties to “the Zionist entity” publicly.

President Morsi has come under harsh criticism both in Egypt and in the Arab world following his letter to Peres, first published by The Times of Israel.
