Ditch the "celebrity entrepreneurs".
Ditch the "celebrity broadcasters"
Ditch the always unfunny "comedians".

Just presenter + fired candidate + audience.
That way we can see more unseen clips and get better insight from the candidates, instead of listening to self-promoting drab every week from guest panelists.

They could add someone from the business involved in the weeks task and either Nick, Karren or Margaret or one of the finalists from a previous series.

That removes one 'makeweight' but keeps useful insights and allows a few more clips.

Audience questions too. as true fans we want those awkward questions answered that the presenter just doesn't or won't ask.
Ruby Wax on the otherhand would ask those questions!!
