The upcoming Assembly elections in Bengal will be a contest between Narendra Modi’s “development model” and the ruling TMC’s “destruction model”, Union Home Minister Amit Shah said on Thursday, while terming Chief Minister Mamata Banerjee as a “failed administrator”.

He said the BJP's ‘Parivartan Yatra’ is not for changing a chief minister, MLA or minister but ending infiltration and transforming the condition of Bengal.

Addressing a rally in Coochbehar, he said the yatra is also aimed at ending corruption patronised by Bua-Bhatija combine. The BJP has been accusing Mamata and her nephew Abhishek, the Lok Sabha MP from Diamond Harbour, of “institutionalising corruption”.

He also spoke about the political killing of BJP workers and warned that the perpetrators will be thrown behind bars.

“This ‘Parivartan Yatra’ is not for changing a CM, MLA or a minister. It is for ending infiltration, it’s for the transformation of Bengal.

“You vote the BJP to power in Bengal. Leave alone illegal immigrants, not even a bird from across the border will be allowed to enter the state,” Shah said addressing a rally before flagging off the fourth of the five ‘Parivartan Yatras’ planned by the BJP ahead of the assembly polls.

The union minister said the BJP is ready to take on the “goons” of the ruling TMC.

“You think that we can get intimidated by the TMC goons? They cannot stall BJP’s march to power. Once we are in power, each and every perpetrator of violence that led to the killing of BJP workers will be thrown behind bars,” he asserted.

He alleged that Mamata Banerjee gets angry at ‘Jai Shri Ram’ slogan, but will herself begin chanting it by the time assembly polls are over.

“If ‘Jai Shri Ram’ is not chanted in India, will it be chanted in Pakistan? You get angry over it because you want to appease a particular section of people for vote bank politics,” he said.

Shah said the upcoming assembly poll will be a contest between the “vikas (development) model” of the Narendra Modi government and Mamata Banerjee's “vinash (destruction) model”.

The home minister said while the Modi government works for “jan kalyan” (public welfare), the Mamata Banerjee dispensation is bothered only about “bhatija kalyan” (nephew’s welfare).
