CAIRO: Six Egyptian presidential candidates are negotiating to settle down their differences and put a final formula of a statement. They will announce the conference results on Wednesday evening, according to an official of Amr Moussa's campaign. However the official said there is no unanimous agreement from all presidential candidates since there is difference of opinion on certain points. He added there is an ambiguity in the general image and opinion. The consultations on Wednesday aim to put down a formula to satisfy all the candidates before the scheduled conference, the source said. He noted presidential candidate Amr Moussa will not attend the conference to be held at 7:00 P.M. His campaign representative Hesham Youssif will attend the conference for him, who asserted Moussa's opinion of holding off the presidential elections until mid 2012.
