"We have got the permission finally from the Ministry of Defence. After media reports, the Centre was forced to give permission as a damage control measure," West Bengal BJP president Rahul Sinha told PTI here.
Modi's schedule remained unchanged and after landing at the NSC Bose International Airport he would board a helicopter to the race course ground, which is controlled by the Army authorities.
Earlier in the day, the party had claimed the Army refused permission for the helicopter to land at the race course ground since it could only be used by the President or Prime Minister and not a political person.
"If they had told us two or three days ago, then we could have made other arrangements. The central government is playing dirty and cheap politics," Sinha had alleged.
The BJP leader said that it was planned to bring Modi by chopper from the airport to avoid traffic snarls.
Sinha said that a three-tier security cordon was in place for Modi's rally with the first being manned by the NSG and Gujarat security officials, the second by the Kolkata police and the third by 1070 BJP cadres under 52 observers.
Six watch towers and CCTV cameras would keep a watch on the crowd.
The Army spokesperson here could not be contacted despite several attempts.
