Guwahati/ Nagaon/ Jorhat, April 12 : Senior BJP leader and Gujarat chief minister Narendra Modi today tore into the Congress-led government in a series of election rallies in Assam, giving a big boost to the AGP-BJP poll campaign.

The BJP leader worked on the crowd, that turned up in huge numbers, by highlighting the Congress government’s failure in providing drinking water despite the Brahmaputra river flowing through most parts of the state.

He lambasted Prime Minister Manmohan Singh, who is a Rajya Sabha member from Assam, saying he had done “nothing” for the state.

Modi addressed the day’s first rally at the Jorhat District Sports Association Grounds where the BJP has fielded Kamakhya Prasad Tasa.

Moving to Nagaon later in the day, he blamed the Congress government for the insurgency and influx. The party has fielded sitting MP Rajen Gohain from that seat.

Addressing a rally in Guwahati this evening, Modi made an appeal to the Election Commission to take suo motu cognizance of an “objectionable” statement made by a senior Congress minister of the UPA government yesterday. The latter had warned Modi not to criticise the Congress or else he would be imprisoned.

Modi said vote bank politics of the Congress have ruined the country and only BJP-led NDA’s politics of development can bring prosperity to the nation and solve its myriad problems.

The Congress today alleged that the AGP, BJP and AUDF had joined hands to defeat the party.

“There is a formal and tacit understanding among the three to defeat the Congress and there is evidence of it,” party spokesman and health minister Himanta Biswa Sarma told reporters in Guwahati this evening.

Providing details of calls made from the cell phone of a PCG member Hiranya Saikia, he said Saikia had in all probability helped in this exercise.

“All the phone calls seen in the call details were made from Saikia’s number to different members of the three parties soon after Sonabor Ali, the AUDF candidate for the Guwahati seat filed his nomination,” he said.
