Hours after he opened a debate on the Rafale deal in parliament, Congress president Rahul Gandhi on Wednesday launched a scathing attack on PM Modi to renew the opposition's demand for a joint parliamentary committee probe into the purchase of the 36 aircrafts. “The cost was changed from Rs 526 crore to Rs 1,600 crore. Why was the cost inflated? Did the Defence Ministry object to it? Who decided to increase the price of the jets? Was it PM Narendra Modi's decision or the IAF's?” asked the Congress President. Rahul Gandhi also accused PM Modi of helping Anil Ambani and Reliance with the Rafale deal.
