Campaigning opens Saturday in Egypt for a May election likely to be won by the ex-army chief who deposed the elected president, after deadly bombings underscored tensions ahead of the vote.
The May 26-27 presidential poll, meant to restore elected rule following the July overthrow of Islamist Mohamed Morsi, is widely seen as a done deal that will place former army chief Abdel Fattah al-Sisi in power.
His only rival, Hamdeen Sabbahi, came third in the 2012 election which Morsi won, and faces a groundswell of support for Sisi since the ouster of the Islamist leader.
