Adam Boulton on Sky has just said that Dimbleby will be moderating the debate on one side of the university before dashing across to the other side to present QT. From that I take it they have separate studios.
The Daily Mail will be sharpening their pencils then - not only have they spent money on one set, they've spent money on another too!
By the way, when it comes to the rules of the debates does OFCOM (and now the BBC Trust) actually have any jurisdiction over them?
I preferred the internet when it had a sense of humour.
