The Guardian, as usual, is a leader on the PO issue.

This article (dated tomorrow, Aug. 22) refers to a PO summit involving Ministry of Defence.
It also mentions the need for contingency plans.

More intriguing is the claim that the government is reluctance to provide info requested under Freedom of Information, with a reference to the matter as being "important and sensitive."
