Our correspondent in Cairo Mike Hanna sent in this update: There is no parliament, no constitution, and the Supreme Council of Armed Forces holds both legislative and executive power:  this is the situation in which Egyptians are taking their next step in what was supposed to be a transition to real democracy.

The runoff in the Presidential election is taking place under the cloud of two Constitutional Court decisions on Thursday.

Firstly, the twenty judges on that body ruled that part of the procedure in last year's parliamentary election was unconstitutional and effectively dissolved the legislative body.  Secondly the court found that legislation banning the political participation of certain officials in the Mubarak regime was unconstitutional and overturned it- this removed any doubt about former Prime Minister Ahmed Shafik's eligibility to run for President.

Some 46 per cent of Egypt's eligible voters cast ballots in the first round of voting;  and half of these votes went to candidates who came third, fourth and fifth and were thus excluded from the run-off.  It is these votes that could well determine whether Mohamed Morsi or Ahmed Shafik becomes Egypt's next president-  and the question is whether the voters disappointed in the first round vote at all.
