Do we know who initiated this interview? It may simply have been the BBC pestering him for an update. If he'd fobbed them off with 'no comment', & that got reported, we'd probably all be speculating on why his reply was different this time!
He appears to be accepting focussed interviews with individual media properties. This is where I am struggling to understand his strategy a bit.
It makes sense that he has to do some domestic media in Germany, because he has to manage the reputation of his office.
Doing foreign english media would tend to suggest his media targets are located in the UK. But then why do Australian and Portuguese media?
And why not do structured media pushes with key properties at once instead of individual sit downs? Structured releases enable him to get a consistent message out - in multiple channels.
I would guess he is just accepting interview requests as they come in, which tends to suggest to me that he doesn't have a proper strategy beyond his initial drop. Now the agenda is shaped by the media who contact him - so its more a reactive strategy. And the fact that it is reactive, tends to suggest media is not a key part of what he is doing as opposed to in the summer.
Strange.
