Paragraph 5

Rules (to be agreed upon from time to time between the Authority and the Secretary of State, or settled by the Secretary of State in default of such agreement) shall be observed as to the classes of broadcasts (which shall in particular include the broadcast of any religious service) in which advertisements may not be inserted, and the interval which must elapse between any such broadcast and any previous or subsequent period given over to advertisements.

The Secretary of State may, after consultation with the Authority, impose rules as to the minimum interval which must elapse between any two periods given over to advertisements, and the rules may make different provision for different circumstances.
