New Delhi, May 20 (IANS): A BJP delegation on Monday met top Election Commission officials and demanded re-polling where violence had taken place during all phases of the Lok Sabha polls in West Bengal and requested deployment of central forces till the model code of conduct is in force.

He was accompanied by Defence Minister Nirmala Sitharaman and senior BJP leaders.

Accusing West Bengal Chief Minister Mamata Banerjee of threatening BJP candidates, poll agents and party sympathisers, he urged the EC to take cognisance of the matter.

"We saw incidents of violence took place till the last phase of polling. There is possibility of violence even after counting of votes. So, we have requested the Commission to deploy the central forces in Electronic Voting Machine strongrooms till the end of counting to allow free and fair counting," he said.

He said the central forces should be there till the model code of conduct is in force.

The senior BJP leaders also appealed to the poll panel to ensure the sanctity of the counting process in Odisha, Karnataka, West Bengal, Madhya Pradesh and Chhattisgarh.

"Independent observers must be sent in these states and CCTV cameras must be installed in all counting stations in the five states," he said.
