Serious Crime Bill [HL]

When the Minister answers my noble friend on the Question of whether Clause 40 is necessary when you have Clause 41, could she tell us whether it has something to do with the fact that in Clause 41, "““A person commits an offence if … he believes … that one or more of those offences will be committed, (but has no belief as to which)””." That means he is vague about what might happen; it might be one of a number of offences. Below, however, we read that, "““the charge or indictment must specify the offences””." I do not understand how those two provisions fit together. I am sorry if I seem confused.
