Nigel already has a show on weekday evenings though, and whilst he did host The Political Correction for a few weeks in addition to this weekday show, it’s probably a bit too much.Perhaps Nigel Farage - he used to do a special 2 hour show every Sunday when he was on LBC. It could also be Portillo - that might be why the Political Correction is back. There is also John Cleese who will be presenting a show at some point.
Good thought on John Cleese, an obscure slot on weekends might be good for him! Similar for Portillo, his show is very much suited for a weekend afternoon.
