Ok, that answers a lot then - I did wonder if it could be because of the election night show - but I thought it would be unlikely they wouldn’t have done it anywhere other than Elstree, having done all the national General Elections from there since the move to NBH. I couldn’t see why they wouldn’t. But the point about Elstree being booked up in the run up to Christmas is a good point i hadn’t thought of - it’s funny that something like Strictly is affecting this year’s election programme!
