Rhetorical question of the day

Iain Dale posts as follows:

Robin Aitken spent 20 years as a BBC current affairs journalist. He's written a BOOK about the experience, called CAN WE TRUST THE BBC? He confirms Andrew Marr's assertion that there is an inbuilt liberal bias within the BBC. The book has received widespread coverage in the press, but Aitken reckons the BBC have put a blanket ban on him appearing on their airwaves. The BBC deny any such ban exists, but the fact remains that not a single programme has interviewed him on his book.

Why Won't the BBC Interview Robin Aitken?
