I think this was the term used in the One Wales agreement to provide some context for the proposed referendum on further powers for the Assembly. It seems a sensible get out clause if the skies start to look a little cloudy as the day approaches. Peter Hain seems a little premature in reporting on the state of opinion, but I don't think it requires over reaction.
As from last week we know there is much detailed work to be completed in preparing the ground for any poterntial referendum and people should keep calm heads and focus on that work in the period ahead. That there will be opposition in some quarters to further devolution is not news and part of a mature response will be to get the home work finished in time.
