New Delhi | Janata Dal (United)'s political adviser and spokesperson K C Tyagi on Saturday made it all but clear that the grand alliance government in Bihar is on the verge of collapse and accused a section of the Congress leadership of repeatedly "insulting" Chief Minister Nitish Kumar.

"The INDIA bloc is on the verge of collapse. The alliance of INDIA bloc parties is almost over in Punjab, West Bengal and Bihar," he told reporters.

The goal and intentions with which Kumar, the JD(U) president, succeeded in bringing non-Congress parties with the Congress have come unstuck, Tyagi said, asserting that their leader was "misunderstood".

Kumar never hankered after a position in the alliance but a section of the Congress leadership repeatedly insulted him, he said.

Tyagi said he could not see as to how the INDIA bloc parties could fight the "all-powerful" BJP.

The Bihar chief minister succeeded in bringing together several parties in Patna but the entire process became so limp that the INDIA bloc has had no joint meetings on leadership and agenda even though the Lok Sabha elections are now round the corner.
