Bharatiya Janata Party (BJP) President Amit Shah on Wednesday hit out at Congress chief Rahul Gandhi for his demand for a Joint Parliamentary Committee (JPC) to probe Rafale deal and accused him of lying over the issue."Your lies to fool the nation are self-evident when Rafale price you quote vary in Delhi, Karnataka, Raipur, Hyderabad, Jaipur and Parliament. But the nation's IQ is higher than yours!" Shah said in a tweet.His remarks came hours after Rahul Gandhi alleged that the government was trying to cover up a "scandal with scandal" and asked why it was "scared" of a JPC probe.Responding to Gandhi's charge and demand, the BJP chief said: "Why wait 24 hours when you already have your JPC - Jhoothi Party Congress?"Earlier, Finance Minister Arun Jaitley in a blog post termed the Congress charges on the Rafale deal as "complete falsehood."Hitting back, Gandhi said the government should then accept a JPC probe.
