That's all for now...published at 17:08 British Summer Time 16 April 2018
This afternoon's session was much slower, more technical and less dramatic than this morning.
But Dr Crawford has many more questions to answer tomorrow - he's booked in for the whole day and we'll have live coverage from 09:45, so join us then.
Mrs Foster will be back in the hotseat on Wednesday and Thursday.
For now, it's good evening from us!
