Egypt’s Supreme Constitutional Court has overturned the ruling that barred senior members of the government of former President Hosni Mubarak from standing for re-election.
The decision now clears the way for Mubarak’s former prime minister, Ahmed Shafik, to stand in Saturday’s run-off for the presidency.
The announcement caused consternation among those protesting against his candidature.
The court also declared void one third of the parliamentary seats won in the first post Mubarak election, dissolving parliament and paving the way for fresh elections.
The weekend’s presidential election sees Shafik take on the Muslim Brotherhood’s candidate, Mohammed Morsi.
