Alistair Stewart or Tom Bradby should host the debates.
Why? Julie has proven herself to be a superb moderator.
I think Alistair or Tom would inject some life into a debate.
Alistair yes, but not Tom. I'm not a fan and he takes forever to get to the point; at which point youve forgotten what he said at the start of the sentence. I'm sure most people won't want the debate running on for hours.
It would be nice to see the debate finish then the News at Ten be presented from the same location with analysts and Julie or whoever does the debate presenting the show aswell.
