Banerjee said her party would try hard to stitch together a federal front of regional parties to form a government after the next polls.
She also expressed her willingness to give outside support to such a government, saying, "If needed, we will give support. We do not have have any lust for power and chair."
Confident of playing a crucial role at the Centre post-election, she claimed that her party was the only alternative to Congress and BJP in the country.
Coming down hard at the UPA governent for price rise, corruption and "non-cooperation" in giving funds to West Bengal, she called for "durniti hatao, desh bachao."
"At the Centre we want a government of integrity and unity and want a change of dynastic rule in Delhi. The country is for all," she told the rally which was held in remembrance of 13 party workers who were killed during a demonstration in 1993 and the day is observed as a "Shaheed Divas".
She also chose the rally to announce that TMC would fight the Lok Sabha election in states apart from West Bengal.
"We will fight the elections in other states apart from Bengal. I will personally campaign in those other states too," she said to loud cheers of the big gathering at the vast Brigade Parade Ground.
