The review is being carried out by the official electoral authority and international observers. Venezuela's electoral authorities say preliminary results of an audit of the vote on President Hugo Chavez's rule show there was no fraud. They say more than 30% of 150 randomly chosen polling sites have been checked so far - confirming the outcome of the vote there.

The outcome of the audit is expected to be published this weekend. [more
