New Delhi: Warren Anderson, former chairman of the American parent company Union Carbide Corp responsible for the 1984 Bhopal gas tragedy, met the President and Home Minister after being released on December 7 that year. Arun Nehru, former minister in the Rajiv Gandhi government, told this to CNN-IBN on Monday. “After being released, he came in a state aircraft to Delhi. He saw the Home Minister (P V Narasimha Rao) and he saw the President ( Giani Zail Singh) -- this is an event which took place and it is much better to clarify. The only one who can clarify is the government,” said Nehru, who was once Rajiv Gandhi's chief strategist. Nehru's statement may expose the Congress to further criticism at a time when it is under pressure to explain why Anderson was released after being arrested on 7 December 1984 when the deadly methyl isocyanate (MIC) gas leak from Union Carbide’s Bhopal plant had killed thousands of people just five days ago. Finance Minister Pranab Mukherjee on Sunday defended senior Congress leader Arjun Singh for his decision as Madhya Pradesh Chief Minister in 1984 to release Anderson. “It is clear in Arjun Singh’s statement, which he had made then that law and order situation was deteriorating. People frenzy was on high, therefore it was thought necessary to move out Warren Anderson,” said Mukherjee on Sunday.
