The result of Assembly polls in four states was 'anti-Congress', Bihar Chief Minister Nitish Kumar said today but rubbished Modi-factor for BJP's victory which was evident in its "below par" performance in Delhi.

"There is no doubt that the results in Assembly elections in four states are anti-Congress. But there is no reason for BJP to jump in joy.

"There is no wave in favour of BJP... The results show that BJP performance will be dismal in the Lok Sabha elections," Kumar told reporters in the Assembly premises.

"The gamble BJP took (by appointing Narendra Modi as its prime ministerial candidate) has doomed it... Delhi is the test case of this," said Kumar, who led JD(U) to severe ties with the BJP after 17 years over the elevation of Narendra Modi as party's prime ministerial nominee.
