Cairo: Hamdin Sabbahi, from the Leftist Al-Karamah party, has demanded a recount in Egypt's presidential election citing many violations.
Sabbahi, who is said to have come third, said conscripts had voted illegally.
According to unofficial results from state media, Sabbahi missed out on the second round by 700,000 votes, The BBC reports.
Sabbahi's spokesman Hossam Mounis said they will legally challenge the election results on Sunday.
"The evidence we have, and that we are still accumulating, shows a big number of violations in many polling centres that would affect the final results," Mounis said.
Sabbahi is said to have gained 21.5 percent of the votes.
Next month's run-off will be between candidates of the Muslim Brotherhood and those loyal to the Mubarak regime.
Muslim Brotherhood candidate Mohammed Mursi has a slight lead over former Prime Minister Ahmed Shafiq, with an almost 25.3 percent votes against 24.9 percent votes for Shafiq.
