BJP National President J P Nadda on Wednesday launched the 'Griha Sampark Abhiyan' in the city as a part of the party's 'Aar Noi Annay' (No More Injustice) campaign in poll-bound Bengal.

The door-to-door campaign is part of the massive public outreach programme BJP has planned in the run-up to the state Assembly election due in April-May 2021.

There was blowing of conch shells and showering of flower petals by women wearing red bordered sarees as Nadda's motorcade reached Bhawanipore area of the city.

Party MPs Locket Chatterjee and Arjun Singh accompanied Nadda as his security tried to hold back the crowd when his vehicle negotiated the narrow lane to take him to some of the houses in it.

"He gave me a booklet and asked me to read it when I greeted him. There was so much crowd and jostling around," a housewife told reporters later.

Nadda visited a few households on Girish Mukherjee Road, a few km away from Cbief Minister Mamata Banerjee's residence, briefly interacted with the locals, heard their problems and requested them to give BJP a chance before boarding the car, party sources said.

"No untoward incident was reported," a police officer present at the spot, said.

Nadda is in Calcutta as part of a two-day visit to the state and will attend several party programmes, the sources said.

On the other hand, in an apparent attack to the BJP without naming it, Bengal Chief Minister Mamata Banerjee on Wednesday alleged that a political party was misusing the Constitution and urged everyone to pray together to save it as well as the country.

Referring to the Constituent Assembly meeting for the first time on this day in 1946, Banerjee paid her tribute to all its members who gave shape to the country's Constitution.

"On this day in 1946, the Constituent Assembly met for the first time. Tribute to all members of Constituent Assembly who gave shape to India's Constitution. These days, 'A' political party is misusing the Constitution. Let us pray together to save our Constitution. Save our India," Banerjee tweeted.

On this day in 1946, the Constituent Assembly had met for the first time in New Delhi in the Constitution Hall, now known as the Central Hall of Parliament.

Assembly polls in Bengal are likely to be held in April-May next year.
