New Delhi, May 11: Bharatiya Janata Party (BJP) spokesman Ravi Shankar Prasad on Monday described the Congress-led United Progressive Alliance (UPA) as an "Ulta Pulta (topsy turvy) Alliance".

Hours after Prime Minister Manmohan Singh questioned Bihar Chief Minister Nitish Kumar''s secular credentials, Prasad said the UPA was a divided house.

"Manmohan Singh looked pessimistic and defeated. The campaign of Congress lacks maturity and no one knows who is saying what. UPA is Ulta Pulta Alliance," Prasad said at a press conference in the capital.

Prasad said the Congress was confused, with some leaders praising Nitish Kumar and others criticizing him.

"Rahul Gandhi praised Nitish Kumar. He said he (Nitish Kumar) did good work, Sheila Dikshit said the same. But Manmohan Singh said he didn''t do good work and didn''t spend the money the centre gave him. The PM said Nitish is an incompetent chief minister, Rahul says the opposite," Prasad said.

"It''s not in the DNA of Congress to run a coalition. It believes in the divine right to rule," he added.

Prasad said the UPA had "collapsed" and the BJP-led National Democratic Alliance "has emerged as the front runner with hope and self confidence".

"The UPA is an alliance which is non existent and filled with pessimism. I would like to remind the prime minister to look inwards, your house has collapsed like a pack of cards." (ANI)
