"Former Union Home Secretary RD Pradhan has already denied the contents. He (Arjun) was not stating facts correctly," former Madhya Pradesh Chief Minister Sunderlal Patwa said.
On whether it was an attempt to shield former prime minister Rajiv Gandhi on the issue, Patwa said "it is clearly visible."
He said that had Anderson not been released under the then Congress Government led by Arjun Singh, things would have been different for the Bhopal gas tragedy victims.
Madhya Pradesh Gas Tragedy Relief and Rehabilitation Minister Babulal Gaur also termed the Singh's claims as "far away from the truth".
"When I met him (Arjun Singh) on the issue number of times and discussed him about Anderson's release, he always told me that he acted on the directives of the Government of India," Gaur claimed.
