The result could have been different had Rahul Gandhi agreed to an alliance with the Trinamool Congress and local hill parties, she said and claimed the poll results will not help the BJP in the upcoming assembly elections in several states.
As the BJP and its alliance partners were on Monday all set to form governments in Tripura, Nagaland and Meghalaya, the Congress said the BJP's "blind quest for power is superseding stability" of the northeast region. Congress emerged as the single largest party in Meghalaya with 21 seats.
With results announced for all 59 seats in Tripura's state legislature, the BJP had won a big majority to form a government on its own in the state, replacing the Communist Party of India (Marxist), or CPI (M).
"My honest thanks to each and every Congress worker who toiled for the party", Gandhi tweeted in the aftermath of the election results.
Congress president Rahul Gandhi, back last night in India from a short vacation, assessed the results of assembly elections in the northeast today, accusing the BJP of "usurping" power through a proxy in Meghalaya. The Congress had a disastrous performance in the state as it failed to win even a single seat.
Elections were held only in the states of Tripura, Nagaland and Meghalaya, where about nine million Indians live, according to the 2011 census. Mr Zeliang had said his party would be happy to form a new government with its old ally, the BJP.
Its ally IPFT, which fielded candidates in nine seats, got almost eight per cent votes.
Another Congress MLA Ratan Lal Nath had also joined BJP two months before the Assembly elections and was disqualified by the Speaker under the anti-defection law. Added to the BJP's two seats and PDF's 4 and one won by an independent candidate, the number comes up to 34, three more than the simple majority mark of 31 in the 60-member assembly. "My honest thanks to each and every Congress worker who toiled for the party", Gandhi said on Twitter. Aware of the growing reach of the Bharatiya Janata Party in the state, and the dual impact of power, money and ceaseless hard work since 2014, the Left was still optimistic of retaining the state. "I will not run away from taking the responsibility", he told reporters in Agartala when asked if he would accept the task of being the state chief minister.
In case of Tripura, the rise of BJP is simply remarkable.
Banerjee's efforts coincide with BSP's announcement that it will support the Samajwadi Party candidate in UP's Phulpur Lok Sabha bypolls to defeat BJP, though BSP chief Mayawati did not call it an alliance.
