Venezuela's three opposition parties have pulled out of Sunday's congressional poll, accusing the electoral body of favouring pro-government candidates
Venezuela's three opposition parties have pulled out of Sunday's congressional poll, accusing the electoral body of favouring pro-government candidates, BBC World news reported.
The head of the main opposition party, Democratic Action, said they felt the result would be biased against them.
However, Vice-President Jose Vicente Rangel said the party was pulling out because it was facing defeat.
Venezuelans will vote for an expanded 167-seat congress, where supporters of President Hugo Chavez have a majority.
Correspondents say that the government has vowed to increase its majority to two-thirds, which would allow it to pass constitutional reforms that opposition leaders strongly oppose.
