Osama Atawiya told journalists that four people had been refused registration. Three were under 40, which is the minimum age requirement set by the law, whereas the other man, Abboud al-Zumr, was still in prison for his part in the 1981 assassination of President Anwar Sadat and had failed to complete the due agreement with his lawyer.
The election commission will finish registering candidates at 8 p.m. local time (5 p.m. GMT) and start examining the documents submitted by the candidates. The final list will be published on August 13.
A candidate should have the support of at least 250 members of parliament and local legislatures. The election campaign will begin August 17 and end September 4.
The current head of state, 77-year-old Hosni Mubarak, has the support of the ruling National Democratic Party of Egypt and is running for his fifth term.
The election will be a break with history in Egypt, as in the past the head of state was elected in a referendum with one name selected by parliament on the ballot papers.
