The People’s Action for Free and Fair Elections (PAFFREL) chairman Kingsley Rodrigo told a news conference he had got the assurance at a meeting with elections commissioner Dayananda Dissanayake.
Rodrigo said the talks were aimed at ensuring a free and fair election.
The elections campaign for the provincial council polls in the North Central and Sabaragamuwa provinces has been marred by violence.
Rodrigo quoted the elections commissioners as saying that it was the first time the decision was made to close polling stations where there are irregularities.
Dayananda was not immediately available for comment.
