The JD(U) was taking cognisance of statements of BJP leaders on NDA's prime ministerial candidate in the 2014 general election but would make its stand clear on this only when it would come up in the NDA, Bihar Chief Minister Nitish Kumar today said.

"We are taking cognisance of all these statements (of Nitin Gadkari and Sushma Swaraj) but will speak on the issue only when it comes up for discussion in the NDA," Kumar said.

"What is the use of speaking over an issue beforehand.... I have never been in favour of opening my mouth before time," he said in reply to repeated questions from mediapersons over comments of BJP leaders Gadkari and Swaraj.

The senior JD(U) leader said he and his party has already spoken as what kind of person should be projected for the post of Prime Minister.

Kumar, known for not keeping good relations with his Gujarat counterpart Narendra Modi, had said in a recent interview that only a person with secular image should be chosen as NDA candidate for the top post, while the BJP president and Swaraj had made it clear that Modi, carrying the stain of Gujarat riot of 2002, should be made the PM nominee.

Asked his chance for the PM post, he said the choice should be from the largest party of the coalition.

Asked why he was not going to Gujarat to campaign for JD(U) candidates in Assembly elections there, he said "They do not require my services."

"I have already told my party that because of my engagements like visit to Pakistan, Adhikar Rally for special status to Bihar and winter session of Assembly (that ended on December 5) I would not be able to go to Gujarat for campaigning", he added.

Kumar said he was going to Kolkata on Friday and would try to meet his West Bengal counterpart Mamata Banerjee.

Asked if the meeting with Banerjee would be a political one, he said, "It will be a courtesy call to the West Bengal CM."

On tribals "capturing" land that the state government had given to establish a campus of Aligarh Muslim University (AMU) at Kisanganj, he said "the state government has provided hassle-free land for AMU branch."

Kisanganj witnessed tension yesterday after a group of tribals armed with traditional weapons descended on the 224 acre land alleging the site was land given to them free of cost by the government for their livelihood and had been wrongfully acquired. BJP MLC Dilip Kumar Jayswal accompanied them to offer puja at the land.

The Bihar CM said nobody would be allowed to take law in their hands on the matter.
