Bolivian opposition Unidad Nacional (UN) party asked the Organization of American States (OAS) to monitor a plan Bolivia is implementing to grant identity cards with Venezuelan technical and financial support, as they fear a fraud may be perpetrated in upcoming polls for the Constituent Assembly next July.

The head of UN faction in Congress Peter Maldonado told Efe he made the request in a letter he sent last Friday to OAS representative in La Paz Bernhard Griesinger.

Maldonado requested OAS to supervise the ID issuance process under which some two million people, according to official figures, are to be granted identification cards, as they are concerned about Venezuela supporting the plan.

"We are deeply concerned that an attempt of electoral fraud may emerge," he said.

He explained that they asked OAS to send electoral observers ahead of the election for the Constituent Assembly.
