A fourth Venezuelan opposition party has pulled out of Sunday's congressional elections, saying it was concerned the balloting would not be fair.
The Justice First party announced its decision Wednesday, one day after the Democratic Action, Project Venezuela and Copei parties announced their withdrawal. Those parties say they are boycotting the vote because the electoral council is biased.
State Department spokesman Sean McCormack Wednesday denied U.S. involvement in the withdrawals, after Venezuelan President Hugo Chavez accused the United States of interfering in the country's electoral process.
Opposition leaders have proposed postponing the vote until they can be assured of a free and fair election.
Venezuelan Vice President Jose Vicente Rangel has denied the accusations and insists the elections will be fair.
