Prime Minister Narendra Modi on Sunday slammed Chief Minister Mamata Banerjee for not implementing several central schemes in Bengal, saying people expected her to show 'mamta' (affection) but got 'nirmamta' (cruelty).

At his first public rally in the poll-bound state here, Modi tore into the TMC government, accusing it of "corruption and misgovernance", and said the ruling dispensation committed "several fouls" in the last 10 years because of which the people have decided to oust it from power.

"Bengal expected 'mamta' (affection) from Mamata Banerjee but got 'nirmamta' (cruelty) in the last 10 years...

The TMC government is just a rebirth of the misrule of the Left Front government in the state," he said.

Mocking Mamata for getting angry over slogans of 'Bharat Mata Ki Jai', Modi wondered why she remained silent when conspiracies were hatched to malign the country.

"She gets angry when she hears slogans hailing the motherland. She gets angry when you demand your rights. But she remains silent when conspiracies are hatched to malign the nation," he said.

"There are some conspirators who're trying to destroy India's image associated with tea and yoga-- made famous by iconic Indians-- all across the world. Has Didi spoken anything about these conspirators? The country will respond to such conspiracies with all force at its command," he said.

Accusing the TMC of criminalising politics, institutionalising corruption and politicising civil administration and police, he exuded confidence of forming the next government in Bengal.

"The people of Bengal have made up their mind to elect a BJP government in the next assembly polls. In the first cabinet meeting of the BJP government, a decision will be taken to implement all central schemes in the state," he asserted.

PM inaugurates host of project in poll-bound state

Modi also dedicated to the nation several infrastructure projects in the oil and gas sector in this port town on Sunday, including the ambitious 348-km Dobhi-Durgapur natural gas pipeline built by government-owned GAIL.

The prime minister said that apart from laying gas pipelines across the country under the Pradhan Mantri Urja Ganga Project, focus is on reducing the price of natural gas.

He also inaugurated an LPG import terminal of Bharat Petroleum, besides a four-lane road overbridge at Ranichak in Haldia as part of the port connectivity highway project.

He also laid the foundation stone for the second catalytic dewaxing unit of IOC at Haldia refinery.

"Gas-based economic systems are India's need and 'One nation one gas grid' is an important project to meet this requirement," Modi said.

He said that apart from Bengal, the Dobhi- Durgapur gas pipeline will benefit 10 districts in Jharkhand and Bihar.
