343.Subsection (2) creates new subsections 5(2) to 5(12) to the Wireless Telegraphy Act 1949 as follows:
	5(2) restricts the ability of a designated person to authorise interception of wireless telegraphy to activity which cannot be warranted or authorised under this Act;
	5(3) requires that where the an authorisation is granted under the Wireless Telegraphy Act 1949, consideration must be given to both the necessity and proportionality of the interception in the context of what is sought to be achieved through it;
	5(4) explains the purposes for which an authorisation under the Wireless Telegraphy Act 1949 may be granted;
	5(5) requires that where a requirement exists to intercept wireless telegraphy which would not meet one of the tests in 5(4) above but would fit within the criteria of this subsection, a separate authority must be sought;
	5(6) requires a designated person to consider whether that which is sought to be achieved through the interception could be done in another way;
	5(10) follows on from subsection (2) and explains that where interception of wireless telegraphy is required to be authorised under the Regulation of Investigatory Powers Act, the fact that the applicant cannot be authorised in this way because he is not mentioned as one of the bodies to which the Act applies does not mean that he can rely upon section 5 to obtain authorisation;
	5(11) explains the meaning of “separate authority”.
Other Authorisations Part V:  Miscellaneous and Supplemental “Designated person” is defined in the inserted section 5(12)
