Egypt's parliament approved an amendment on Thursday to a law that would ban members of ousted president Hosni Mubarak's regime from standing for public office.

The law, which has still to be approved by the ruling military council, could see several former officials including ex-intelligence chief Omar Suleiman disqualified from standing in a presidential election scheduled for next month.

The amendment to the political activity law "bars any president, vice president, prime minister or leader or (senior member) of the now-dissolved National Democratic Party from exercising political rights for 10 years," the MPs said in a parliamentary session aired live on television.

The law still needs to be ratified by the Supreme Council of the Armed Forces (SCAF) which took power after Mubarak was ousted on February 11 last year.

The text applies to Mubarak-era officials who served in the 10 years prior to the date of his ouster, which would also disqualify Ahmed Shafiq -- the last premier to serve under the longtime strongman.

Registration for Egypt's top job closed on Sunday, amid last minute twists and turns that have shaken the political race.
