Thank you very much for your question.
I would first say that it was the role of the Privy Council Office, our colleagues in the security and intelligence and the director there who brokered these engagements. It's not SITE directly; it's through the Privy Council Office.
They would send invites out to, I believe, registered political parties. From my recollection, an invite would have been sent out explaining what the intent and purpose was, and then there would be a follow-up for those who were willing to engage. It was really on the invitees to accept or decline.
The Privy Council Office is the body that would have done that.
Thank you.
