Nicaraguan Opposition continued to demand a new recount of Sunday's municipal election votes.
They have not ruled out demand that the result be annulled and are organizing street protest to pressure election authorities.
"We are not recognizing the recount done by the Election Commission (CSE) because we wanted it to be done countrywide and in the presence of independent observers," said Eliseo Nuñez, from the press team for the movement that supports the opposition candidate for mayor of Managua, Eduardo Montealegre.
The Electoral Tribunal carried out the review of the voting in Managua with contradictory versions about the physical presence of the opposition.
There was an air of uncertainty on Thursday in Nicaragua, after a round of violence that erupted when the opposition refused to accept the tribunals decision to only review the municipal polls on Sunday in Managua, and without independent observers.
Preliminary results from municipal polls give the win to the Sandinistas. The oppositions denies this.
Preliminary results early Monday morning issued by the Supreme Electoral Council, CSE, suggest a decisive victory for the official National Sandinista Liberation Front in the municipal elections held Sunday in Nicaragua.
In the midst of a political polarization the elections have come to be about the Sandinista President, Daniel Ortega.
Almost 4 million Nicaraguans are eligible to vote this Sunday to elect almost 3400 officials, including Mayors, Deputy Mayors, among many others from 5 different parties. It is expected to come down to the major parties Partido Liberal Constitucionalista (PLC, right) and Frente Sandinista de Liberación Nacional (FSLN, left).
