Maybe Look 'ULL would be better scaled back to about the same level of sub-opt as Look East (Cambridge), now that sufficient "saving face" years have passed?
Though Cambridge is now a full 30 minute opt at 1830 so there isn't a sub-opt at 1830 or 2225 (not sure if they are pan-regional at lunch time still)? Do you mean sharing Breakfast bulletins and non-News opts with Leeds?
Breakfast, Lunch and Weekends joint service from Norwich.
1830 and 2225 full split from Cambridge and Norwich.
Presenters shared e.g. Amelia will cover Cambridge at times and Amanda presents Sunday bulletin.
Christmas last year saw some bulletins come from Cambrudge instead of Norwich.
