Union minister Venkaiah Naidu on Thursday lashed out at the Congress over former Home Minister P Chidambaram's remarks on the Kashmir unrest and said that his remarks showed the level of inconsistency of the Congress.

"The only consistency in the Congress is its inconsistency," said Naidu in New Delhi.

"The statement of the former Home Minister P Chidambaram shows the casual and reckless manner of the Congress when discussing Kashmir," he further said.

"Congress has once again displayed its insensitivity on the Kashmir issue. Its own leaders are not in consonance... One day, Kapil Sibal says something. The next day, Congress disowns it," he said.

"These statements and contradictions show lack of maturity and signs of political opportunism," Naidu said, referring to how the Congress distanced itself from Chidambaram's remarks."Their utterances are totally out of sync with the mood of the country," Naidu further said.

"Why is Congress trying to exonerate Pakistan? I appeal to these parties to be realistic and understand the sentiments of the people."

Naidu's reaction came a day after Chidambaram had blamed the PDP-BJP government for the unrest in Kashmir Valley and said the statements of Prime Minister Narendra Modi have "exacerbated" the crisis.
