Egyptian voters in a referendum on the constitution held this week have overwhelmingly approved a new constitution, according to an interior ministry official.

The result of the two-day ballot could pave the way for a possible presidential run by army chief General Abdel Fattah al-Sisi.

“Turnout so far may exceed 55 percent and the approval of the constitution is perhaps more than 95 percent,” Major General Abdel Fattah Othman, director of public relations for the ministry, told private satellite channel Al-Hayat.

The result comes as no surprise. There was little or no trace of a campaign against the new constitution. It was supported by Egyptians who also backed the army overthrow of Islamist president Mohamed Mursi in July.

After ousting Mursi, Sisi cracked down heavily on Mursi’s Muslim Brotherhood, now classified as a terrorist organisation.

The Muslim Brotherhood called for a boycott of the vote.
