"The revelations made by Jayanthi Natarajan in her letter to Sonia Gandhi, which have become public, are a matter of great concern and is a serious issue," he said.

He said as environment minister, it is his duty to review those specific files where extraneous influence has been alleged as per the letter.

"I will definitely review those files and see what are the facts," Javadekar said.

Natarajan had written a letter to Congress President Sonia Gandhi alleging that she had received specific requests from Rahul Gandhi on environmental clearances and consequently had rejected big ticket projects.
