Ahead of the Assembly polls in West Bengal, the BJP has chalked out a programme to launch a massive campaign in the state by its central leadership.

Union ministers Nitin Gadkari, Rajnath Singh, Smriti Irani and party president Amit Shah will hold rallies across the state this month, party sources said.

The campaign would start with Union Road Transport and Highways Minister Nitin Gadkari's rally at Malda in North Bengal on January 18, while Union Home Minister Rajnath Singh will hold a public meeting on January 21 at Barasat near Kolkata.

Union HRD Minister Smriti Irani would address a rally at Burdwan on January 22, which will be followed by the rally of party president Amit Shah at Howrah on January 25.

The party would also organise processions, meetings and other modes of campaign statewide soon, the sources said.

Launching of the campaign by BJP senior leaders followed Union Finance Minister Arun Jaitley's meeting with state leaders yesterday.

Ruling out electoral alliance with any of the three major political parties in the state, Jaitley had said the party would focus on key issues to carve out its own political space on the basis of issues where the party has clarity and where unrest is brewing among people at grassroot level.

"Those who have destroyed Bengal and those who have destroyed the country are now sending signals to each other," Jaitley had said referring to talks of an alliance between Congress and the CPI(M).

On the other hand, "the ruling TMC is trying to chart out its (own) course," Jaitley added referring to the other major political force in Bengal.

Jaitley had hinted that BJP's policies on economic development and party's views to prevent infiltration into the state, besides no compromise with 'anti-national elements', could be party's key focus area in the state.
