Interim Egyptian president Adly Mansour promulgated Saturday a law setting the stage for an election later this year to replace ousted Islamist president Mohammad Mursi.

The election is seen as a major step in a roadmap outlined by the interim authorities after the military deposed Mursi in July.

Army chief Abdel Fattah al-Sisi, who has emerged as Egypt's most popular political figure, has not yet announced his candidacy but aides say he has decided to stand.

Officials close to Sisi told AFP that he would step down as defense minister after the law was promulgated.

The law sets out the basic qualifications for candidacy and includes a measure criticized in some quarters that make all decisions by the electoral committee before and after the vote final and not subject to appeal.

With the adoption of the law, the electoral committee can now set a date for the election scheduled for this spring, presidential adviser for constitutional matters Ali Awad told a press conference.

It stipulates that presidential candidates be university graduates at least 40 years of age who have completed their military service and  have Egyptian parents.

It bans any candidates who have themselves acquired a foreign nationality, or whose parents or spouse have.

It also stipulates that candidates need to secure the signatures of 25,000 voters from 15 provinces to qualify.

And it sets a 20 million Egyptian pounds ($2.8 million/2 million euro) ceiling for campaign spending ahead of the first round and five million pounds in case of a run-off.

In January, voters approved by 98.1 percent a new constitution that grants the military extensive powers but lacks much of the Islamist-inspired wording of the 2012 charter adopted under Mursi.

Under the charter, Egypt is to start procedures for parliamentary elections within six months of its adoption.

The decision to ban appeals was taken, in part, to speed up the electoral process given "the nature of the transitional period the country is going through and the security and economic crisis," Awad added.

More than seven months after Mursi's overthrow, Egypt remains battered by protests and militant attacks that have damaged its vital tourism industry and scared off investors.

Many Egyptians, weary of the three years of turmoil since the 2011 toppling of strongman Hosni Mubarak, view Sisi as a strong hand who can restore stability.

But the ban on appealing electoral committee decisions has already drawn criticism.

Emad Hamdy, is a spokesman for the leftist Popular Current, whose leader Hamdeen Sabahi has already announced his candidacy.

"The ban gives negative signals regarding the transparency of the election," Hamdy said.

He added that "the president issued the decree without submitting it to a public debate... and political forces have not seen it until now."
