NEW DELHI: Union minister Arun Jaitley on Tuesday targeted the Congress party which had earlier questioned the involvement of the Comptroller and Auditor General ( CAG ) in the decision-making process of the Rafale defence deal .In a Facebook blog, the Union minister said that the accusations against CAG Rajiv Mehrishi are “lies” peddled to save the dynasty, an apparent reference to the Nehru-Gandhi family.The blog comes on a day when Congress president Rahul Gandhi held a press conference and claimed that Mehrishi, who was entrusted with the task of making the CAG report on the Rafale defence deal, was himself part of the decision making process on the deal."In 2014-15, the present CAG was Secretary (Economic Affairs) in the Ministry of Finance. Being a senior most at one point in time, he was also designated as the Finance Secretary. I say this without fear of contradiction that no file or paper relating to the Rafale transaction ever reached him nor was he in any way, directly or indirectly, associated with the decision making on defence purchases," Jaitley wrote.The Union minister dismissed opposition's allegations on the pricing of the Rafale fighter jets."The dynast knows that his 500 crore vs 1600 crore kindergarten argument was a fictional story," he added.Jaitley also slammed a media report which had claimed that the defence ministry had objected to "parallel negotiations" between the Prime Minister's Office and stakeholders on the French side on the Rafale defence deal.Without naming Gandhi, Jaitley said "the dynast" and his friends have in the past even attacked the Supreme Court when it rejected the writ petition on Rafale.He said the entire pricing argument of the Congress was factually wrong and the procedure argument that there was no Defence Acquisition Council, no CCS, no Contract Negotiation Committee was a blatant lie.Jaitley said truth is both precious and sacrosanct and in mature democracies those who deliberately rely on falsehood are banished from public life."In modern world dynasties inherently have their limitations. Aspirational societies abhor kingdoms. They insist on accountability and performance. But the grand old party of Indian politics has sadly become a captive of a dynasty. Many of its senior leaders lack the courage and moral authority to advise the dynasts to change course."This trend started in early 1970s; climaxed during the Emergency and has continued ever since. The 'slave' mentality of senior leaders convinces them that they must only sing the song scripted by the dynast. A contrarian opinion will cost them their political career. When the dynast speaks lies, they all join the chorus," Jaitley said.
