Authorities in Egypt are to release official results on Tuesday of a constitutional referendum that the ruling Islamists say they have already won, but which the opposition alleges was marred by fraud.
  
The numbers, to be given out by the electoral commission in a news conference scheduled for 7:00 pm (1700 GMT), are unlikely to resolve the country's political crisis.
  
The opposition National Salvation Front has already vowed that "the referendum is not the end of the road".
  
Weeks of sometimes violent protests have challenged the authority of President Mohammad Mursi.
  
The opposition claims polling fraud skewed the result, and stresses that just 16 million of Egypt's 51 million eligible voters took part -- many of them from the under-educated poorer classes -- raising questions of legitimacy.
  
Mohamed ElBaradei, a Nobel peace prize laureate and former chief of the UN atomic energy agency who heads the National Salvation Front, admitted to the US network PBS on Monday that the referendum would be adopted.
  
"It is going to pass, but it's a really sad day in my view for Egypt, because it is going to institutionalize instability," he said. The new charter should be treated as "an interim one" until another is written up on the basis of consensus, he said. "So far, Mr Mursi has been not reaching out to the rest of the country. And he needs to do that, because this is where the reservoir of the qualified people who can jump-start the economy," he said.

Attention is now turning to legislative elections Egypt will have to hold before the end of February, if the new constitution is declared adopted.
