"It's IOA's considered opinion that Dow Chemical should be removed as sponsors of the Games because the very presence of this company is against the spirit of Olympic ideals," IOA acting president Vijay Kumar Malhotra said in the letter.
"IOA urges International Olympic Committee to urgently take this matter up with the organisers of the London Games and also convey our concerns to them and ensure matter is sorted out amicably keeping in view the sentiments of the millions of people," he said.
"Even Britain's Shadow minister for Olympics Tessa Jowell, who was in Delhi last week, had asked the Games organisers to drop DOW Chemical's as the sponsors," he added. Dow had bought United States chemical firm Union Carbide, whose plant was responsible for gas tragedy that took place in Bhopal in 1984 killing and disabling thousands in one of worst industrial disasters in recent history.
In the letter to IOC President Jacques Rogge, a copy of which has also been sent to London Olympic Games Chairman Sebastian Coe, IOA also said Dow Chemical's claim that the Bhopal issue has been settled was not correct.
"A false campaign has been launched by the DOW Chemical's saying that matter has been settled. It is not correct. The case is still pending in the court and no final compensation has been made," Malhotra said in the letter.
"IOA has received representations from several former Olympians, hundreds of suffering people, NGO's and agencies working among the thousands of Gas victims, protesting the London Games Organisers link with Dow Chemicals," the letter said.
