Some media outlets have been reporting what we all expected in regards to the split in the next series. That the BBC told moff it was happening, rather than him going along to tell them its what he wants.
What they are also saying, however, is that the BBC wanted to move the show, to help boost the ratings of Strictly Come Dancing, which last year too a hammering in the ratings.
While if this is fact, we will never officially know, it does bode well for the show that the BBC trusts its popularity enough to shift it around the schedules in an attempt to boost the ratings of other shows. Let's just hope that they see sense and move it back if the newer time slot doesnt work
