There's an interesting article on the BBC website by Mark Easton about the "healing process" and towards the bottom of it, there's reference to a Citizens Convention on UK Democracy involving, well, a heck of a lot of people:
Over the next two years, the Citizens' Convention on UK Democracy will attempt to engage 10 million people in what it describes as a "UK conversation". Thousands will receive a formal invitation to participate in a convention, their names selected by civic lottery. Among the issues that will be considered are the voting system, the future of the House of Lords, devolving power to local and regional bodies, how politics should be paid for and whether the UK should have a written constitution. A number of senior MPs from across the political spectrum have agreed to help ensure that the conclusions of the convention are considered by Parliament.

Would you participate if asked, and if so, what would you say?
