Defence Minister A K Antony, who has ordered a Central Bureau of Investigation (CBI) probe into the alleged scam in a Rs. 3600 crore defence helicopter deal with an Italian firm, today, said that strongest action will be taken against those found guilty under the integrity clause. Asserting that the government will not tolerate any form of corruption, Antony said that India will blacklist Finmeccanica SpA(SIFI.MI) and cancel its deal to buy 12 helicopters from the Italian defence group if allegations of bribery are proven against the company. The Defence Minister said that two inquiries are being conducted, one in Italy and one in India. Antony further said there has been no information on alleged involvement of former Air Chief S.P. Tyagi's family in the deal. The arrest of Italian company chief in Milan prompted the government in India to order a CBI probe.
