Thiruvananthapuram: Hours after the poll trends indicated massive rout of the ruling-LDF in the Lok Sabha polls in Kerala, Chief minister Pinarayi Vijayan said the defeat was "unexpected" even as the Congress demanded his resignation on moral grounds. Vijayan, who issued a release instead of meeting the media after the setback, said his party would examine in detail the factors which led to the dismal performance.

"It was the political stand taken by the LDF that resulted in BJP failing to get any seats in the state. The opposition of the people of the state to the BJP government at the Centre has become favourable for the Congress in the Lok Sabha polls in the state," the Chief Minister said, adding his party would examine in detail how the anti-BJP mood helped the Congress. Senior Congress leader Ramesh Chennithala, who led the party to an impressive win in the state despite being defeated in rest of the country said Vijayan was theGorbachev of Indian communist party.
