Parliament in Egypt has voted for a law that would ban some senior officials who served under former president Hosni Mubarak from standing for president in the forthcoming elections.
If it takes effect, the law will disqualify former vice-president Omar Suleiman who declared his candidacy last week.
However, the BBC reports the measure is likely to be blocked by the ruling military council.
The justice ministry has already said the new measure is unconstitutional.
General Suleiman was the head of Egypt's intelligence service for 18 years, before taking over as vice-president just before Mr Mubarak resigned.
