My thoughts also go out to all the families who've suffered deep and enduring loss. Could I add to the comments that were made by my colleague Dawn Bowden on the issue of the ability to encourage and support whistleblowers on the front line, but also to encourage people to speak out at board level as well? Because it does seem to me that one of the failures here was the lack of confidence to challenge at board level and the lack of information put in front of that board. And I'd appreciate his thoughts, bearing in mind the progress that has been reported, but also the need for fundamental change at board level, as to whether we are now confident that board members are confident to challenge, to ask questions, to contradict, because that is also a point of failure here and we need to challenge that. Is he confident that the board is now fundamentally changing in that way?
