Campaigning builds in Egypt election

Hosni Mubarak's former spy chief, Omar Suleiman, has formally entered the race to become Egypt's next president.

It has prompted speculation that he will have the support of the country's ruling generals.

One of his main rivals, the Muslim Brotherhood's candidate, Khairat al-Shater, said Mr Suleiman's nomination was an insult to the Egyptian people.

He said his rival could only win by forgery and, if that happens, "the revolution will kick off again".
