Will review each file mentioned by Natarajan in her letter: Javadekar

Minister of State (Independent Charge) for Environment, Forest and Climate Change Prakash Javadekar on Friday termed the substance of former union minister Jayanthi Natarajan's letter to Congress president Sonia Gandhi as 'serious', stating that it was an insight into the extraneous influence in the working of the UPA Government.

"The revelation made by Jayanthi Natarajan's letter to Sonia Gandhi, which was published today, is a very serious issue. Natarajan has traced how members of the party exercised extraneous influence in the working of the government. In my capacity as the present Environment Minister, it is my duty to review each issue and file mentioned by Natarajan in her letter," Javadekar told ANI.

Earlier in the day, an English daily published a letter by Natarajan to Sonia Gandhi, dated November 2014, in which she had stated that she was quitting the Congress due to 'political interference' and alleged that she received 'specific requests' from party vice president Rahul Gandhi on environmental clearances.
