The campaign of Hamdeen Sabbahi, who came a surprise third in the preliminary results of the presidential polls running on a pro-revolution ticket, announced a press conference on Saturday evening at 8 pm in the campaign headquarters in Mohandissin.

The campaign did not specifiy the reasons for holding the press conference.

Nasserist candidate Sabbahi, whose platform had social justice as a main element, fought an impressive electoral rearguard action, finishing a not-so-distant third with 4,739,983 of the votes (21.6 per cent)

Muslim Brotherhood presidential candidate Mohamed Morsi and last Mubarak-era prime minister Ahmed Shafiq appear to have made it to the final, two-horse race in Egypt's hotly-contested presidential elections, after coming in first and second with 5,553,097 (25.3 per cent) and 5,210,978 (23.7 per cent) votes respectively in the first round of balloting.

The results, expected to be made official on Tuesday, leave Egypt's secular revolutionary forces in a quandary, with many reluctant to vote for either candidate.

Egyptians will choose between the two candidates in a runoff vote slated for 16 and 17 June.
