No, they should have got the presenter or a panel of guest presenters to ask the questions IMO, as happens in most US Presidential debates.
Essentially what I want to know on the issue, is “what are you going to do”, “by when is it going to happen” and “how will your plan be paid for”
For me, “student activist asks about climate change”; “Brexit party deserter asks about Brexit”, “foster carer asks ‘wont somebody please think of the children?’” is just sooo obvious it’s untrue.
