I am aware that you did raise this with the First Minister previously. I think that it was probably about three years ago now. Of course, we welcome all forms of debate on public policy matters in Wales. But, as you say, as Ministers, we consider very carefully events that we speak at—whether we accept invitations to speak at commercially organised, fee-charging events. We have to take a lot of decisions around those, taking a lot of things into consideration. Our officials are the same. They have to consider invitations as well on that basis, if there is a fee-charging event. They need to assure themselves that there is a clear public benefit about them participating. Again, you may be aware that the previous Permanent Secretary wrote around that, following the First Minister's answer to you. I think that it's really important that, obviously, if an official takes part in an event—if a civil servant takes part in an event—there is no perceived breach of political impartiality. But certainly, as Ministers, we take those decisions based on the impact that it would have.
