New Delhi: While keeping mum about who would be its Prime Ministerial candidate, the BJP on Monday strongly defended Narendra Modi's Sunday speech slamming the Congress.

Modi, who is being seen as a likely contender for the Prime Minister's post from the Bharatiya Janata Party (BJP), Sunday lashed out against the Congress and the Nehru-Gandhi dynasty, saying that the Congress had always kept the "family" above the nation.

"Whatever Modi said, he said it with certification," BJP spokesperson Sayed Shahnawaz Hussain said on Monday. He also flayed Congress leader Mani Shankar Aiyar for calling Modi a "snake" and a "scorpion".

"Scorpions and snakes come out from Mani Shankar Aiyar's mouth," he said. Asked whether the BJP had accepted Modi as its prime ministerial contender, Hussain said: "We have said that this decision would be taken by the parliamentary board at an appropriate time. Party president Rajnath Singh has also asked leaders not to comment on the issue, so I will not make any further comments."

Asked if the Wharton School cancelling Modi's lecture meant he was yet to be accepted internationally, Hussain said: "Modi never organised the lecture, the university invited him. In democracy, the acceptance of people is all that matters."

Asked about Modi's praise for President Pranab Mukherjee, Hussain played it down saying BJP had a "big heart" and praised those who deserved it.Modi, in his speech at the BJP's national council meet Sunday, called Prime Minister Manmohan Singh a "night-watchman" and heaped praise upon Mukherjee, saying he would have been a better Prime Minister.
