Mamata Banerjee, whose party Trinamul has suffered a significant blow from the BJP in Bengal, today congratulated all the winners and said 'all losers are not losers'.

'We have to do a complete review and then we will share our views with you all. Let the counting process be completed fully and the VVPATs matched,' Mamata tweeted.

Both the Congress and the Left parties were muted in their reaction after trends clearly showed they were heading towards another poll rout after 2014.

If the trends stay until the final results, the BJP would have improved on its 2014 performance when it had won 282 seats on its own in the 543-member Lok Sabha.

Adding the seats won by its allies, the BJP-led National Democratic Alliance could win 343 seats, up from 336 in 2014.

Staring at a massive defeat of the party, Congress spokesperson Jaiveer Shergill said: 'The Congress party is feeling dejected and the trends are not in line with the expectations of the party. I would not jump to the results till complete counting has taken place.... If they (trends) hold, then the Congress needs to introspect as to why it's campaign failed to resonate with the people of the country.'

Immediately after the poll outcome, cracks appeared in the opposition camp with CPI national secretary Atul Kumar Anjaan saying decisions taken by Rahul Gandhi led to divisions within the Opposition. He asserted that the policies of the Congress scion opened the doors for Modi's victory.

'We have some setbacks and we find that unfortunately the Congress didn't perform up to the mark,' senior leader of Nationalist Congress Party Majeed Memon told a TV channel.

'This is a clear mandate for the Modi-led BJP government.... Caste combination looks good on paper but merely caste combination does not work. You need a big loud message that the Opposition did not have,' Yogendra Yadav of Swaraj India said.
