New Delhi /Chandigarh, Dec 22 (ANI): The BJP on Sunday mocked the resignation of union environment minister Jayanti Natarajan to serve the Congress party, saying these mechanisms cannot save the party's debacle in the upcoming general elections. The Congress, however, has maintained that the step was taken as she wanted to work for the party. In a shake up ahead of the Lok Sabha elections, Jayanthi Natarajan resigned on Saturday as the Minister of State for Environment and Forest for 'party work'.
