Al Jazeera's Sherine Tadros, reporting from outside the police academy, said the judge in the case has the right to delay the verdicts for the case against Hosni Mubarak and his two sons, Gamal and Alaa, but that observers say that this is unlikely.

"What's more likely to happen is he will read out the charges for each of the defendants and hand down either sentences or even acquit, as he sees fit," said Tadros, adding that appeals to potential verdict could meant that it could take years for the sentences to be carried out.

She added that if Hosni Mubarak is given a prison sentence, it's also unknown where he will serve it, as he is currently being kept at a medical centre.

Tadros also said that the situation is tense, and that there is a security presence "like we haven't seen before."

"We're talking about 20,000 security personnel, over 150 tanks, securing just this area and the surrrounding area...we're in a very politically charged atomosphere."
