The Office of Fair Trading (OFT) already has the power to use covert human intelligent sources (e.g. informants) as well as direct surveillance methods (including bugs and taps) for anti-trust investigations. These powers are subject to a requirement for authorisation under the Regulation of Investigatory Powers Act 2000. The Secretary of State has made an Order imposing specific requirements when using covert surveillance to obtain information that is subject to legal privilege. Under the Order, covert surveillance can only be used where it is in the interest of national security, for the purpose of preventing or detecting serious crime or in the interest of the economic well-being of the United Kingdom.
