Serious Crime Bill [Lords]

I want to seek clarification from the Minister on the question of oral authorisation that he has identified as being necessary. Section 60(9) states that any"““authorisation…shall be in writing signed by the officer giving it””," and that it"““shall also be given in writing or, where that is not practicable, recorded in writing as soon as it is practicable to do so.””" That wording suggests that it is possible to give an oral authorisation and to record it in writing later. That seems to be the oral authorisation that the Minister is describing. Does he therefore agree that these circumstances are already covered by section 60(9), or is he receiving different advice on this?
