So they told you 'they were very careful to make sure they didn't mention anything about anyone else's submission'? That wasn't very confidential then!
They just told the delegation who attended from CTWD that the meeting was confidential and to make sure when they reported back to the rest of the committee we were aware of that. As far as I can recall we were told nothing, either the delegates or the rest of the Committee about any body else's submission. I may be wrong about this but a lot as happened since that meeting.
We were guaranteed complete confidentiality on all aspects of our submission and no aspect of anyone else's submission was discussed with us, what bit of that is hard to understand?
