Not Nat

Have you ever seen an interview with Iain Duncan Smith? They are extremely rare, because he is so bad at them.

Even when they occur, such as some months ago on Newsnight, he is never asked about his own area of responsibility.

The same was true when he was on Question Time last year. There were no questions on his supposedly popular benefits policies. Not one.

Come to that, it is clear, on the rare occasions that Prime Minister's Questions is still held, that David Cameron cannot even go through the motions of defending what is in any case his indefensible record.

That is why he, too, almost never gives interviews, and is running scared of the Leaders' Debates.

No one from his party would appear on this afternoon's Daily Politics to answer Andrew Neil's questions about immigration.

But we are told that Natalie Bennett is the one with the problem? Of course she is. Of course.
