New Delhi, Apr 15 (IANS): The Bharatiya Janata Party (BJP) here on Sunday slammed the Congress President for attacking Prime Minister Narendra Modi continuously over the Rafale fighter jet deal and said Rahul Gandhi's public utterances reflected his frustration.

"Rahul Gandhi does not seem to have received any lesson in the ethos. His mother does not seem to have either known or imparted what are the real traditions or what is the kind of acceptable behaviour in public life," BJP Spokesperson G.V.L Narsimha Rao said.

"As a result, we have seen Rahul Gandhi degenerating even as the Congress has been losing its popularity over the last five years, more so after he assumed the Congress President's office," he said.

Addressing reporters at the party headquarters, he alleged the Congress President's behaviour had deteriorated. "His public utterances only show frustrations of the Congress of not being able to reverse the negative trend and thus the negative vibes," he said.

On the candidature of Congress MLA Lalit Nagar from Faridabad parliamentary seat, the BJP leader asked why the Congress President has fielded a "benami" as its candidate. "Is this out of pressure or out of love? Doesn't it establish that those involved in property scandals are extremely close to the Gandhi family," he said.

Rao alleged Lalit was brother of Mahesh Nagar who was allegedly involved in many land deals linked to Rahul Gandhi, Robert Vadra and Priyanka Gandhi Vadra.
