I've seen a lot of this on Twitter tonight, I think she's scrutinised and criticised more than most UK politicians - she just generally handles scrutiny extremely well.
The AN interview went as I'd expected and I think over the week we'll see that the FM handled it better than most - each point in the NHS 'steamroller' at the end would have been answered had sufficient time been given but again that's what he'll do to them all over the week
(I think, although I may be wrong, that he went with dirty water being the cause of the recent heartbreaks!?)
