I'm sure Alex would have directed us to this in due course, but I spotted it whilst surfing today. Below is a link to the executive summary of the Wilton Park conference. If Alex wants to act as chair, we could have a discussion on the points made in the document. If you don't have the time Alex, a round-table open discussion could also draw some points out of this I think.
Enjoy
