It’s too late for that. They’ll have contracts in place, not just for the cast but all the crew, catering, etc. All that needs to be paid for and people will say it’s a waste of taxpayers money (based on the licence fee, which the tabloids will also whip themselves up about).
All those camera operators and make up artists etc won’t be able to necessarily find the same level of work even if the BBC does have some form of cancellation clause which means they don’t need to pay them. It would leave a lot of ordinary people out of pocket.
What would they fill Saturday and Sunday schedules with until Christmas? Not to mention the ITT slot (which is admittedly easier with repeats of something)
What difference will a year make except people’s memories will have faded and it will suddenly be a case of they never should have cancelled it, it’s all just such good family entertainment.
Don’t get me wrong there needs to be change at the top and the investigation into both claims has taken way too long but cancelling it at this stage isn’t that easy.
