On 15 May 2009, the Secretary of State for Business Enterprise & Regulatory Reform (now Business, Innovation & Skills) issued a "special intervention notice" in relation to the proposed acquisition by Atlas Elektronik UK Limited of QinetiQ's Underwater Systems Division. The effect of this notice is that the Office of Fair Trading will be required to carry out an investigation into the merger even though the acquisition does not meet the normal test for investigation under the Enterprise Act 2002. The reason the deal raises concerns is that it involves a government contractor and raises questions of national security in the public interest.
