Egypt's opposition alliance says it is gearing up for mass rallies across the country against the highly contentious Islamist-backed draft constitution and to denounce violations that they claim were rife during a first round of voting.
Tuesday's protests follow closely on new salvos in the conflict between Egypt's Islamist President Mohammed Morsi and the judiciary.
On Monday, Egypt's most prestigious tribunal, the Supreme Constitutional Court, denounced a top Morsi aide who distributed a statement labeling the court as an "anti-revolutionary" force. It said the "spreading of false news" was punishable by law.
Meanwhile, another branch of the judiciary announced its boycott of the second round of referendum voting, while the embattled Morsi-appointed prosecutor general submitted his resignation.
