Worth noting though that Britain's Got Talent is filming judges auditions in Manchester on the 9th/10th, so if David Walliams is still doing the first week he'll be missing one or the other.
Still an absolutely idiotic decision at a time when the news, and analysis of it, has never been more important. Hope it flops out of the gate at 10pm so the switch to the more suitable post-news slot is made sooner rather than later. Well, either that or the news is forced to 10pm after Trump accidently presses the big red button when trying to send a tweet.
Shouldn't that have been posted in the "John Logie Baird has Invented Television"
