Paraguayan President Nicanor Duarte Tuesday denounced that "troublemakers" from Venezuela and Ecuador traveled to the Paraguayan capital city "to cloud elections" where leftist former bishop Fernando Lugo is leading polls.

"Troublemakers from Venezuela and Ecuador came here and are staying in hotels downtown to cloud elections," said Duarte to local radio stations, reported AFP.

The Paraguayan pro-government sector claims that Lugo -the front runner in polls- is receiving support from Presidents Hugo Chávez (Venezuela), Evo Morales (Bolivia), and Rafael Correa (Ecuador).
