Alastair Campbell "piling into" the Hilary Mantel / Duchess of Cambridge imbroglio

And here we see Alastair Campbell "piling into" the Hilary Mantel / Duchess of Cambridge imbroglio scandal nexus, thus confirming his new position at the fag end of media interaction (commenting about comments about comments about comments).

Of course, Alastair Campbell chooses not to tell us that the Prime Minister was simply responding to a question he was asked.  David Cameron could have adopted a stuffy Macmillan-like response and waved the question away as "not serious dear boy"; or he could have given the usual evasive politician's answer of "I have not seen the document you refer to"; but instead he just answered honestly and said what I would guess 90% of the general population would say.  What is notable is that Ed Miliband seems to be so insignificant that no-one has yet asked him what he thinks.

It was, after all, a reasonably major item on the Today programme this morning.
