Largely as a result of a recent case in the EU Court of Justice (Inter- Environnement Bruxelles ASBL v Region de Bruxelles-Capitale), DCLG is now formally following the Strategic Environmental Assessment (SEA) Regulations and is undertaking a formal consultation on the revocation of regional strategies. The exercise undertaken last year, which was consulted on in late 2011/ early 2012, was "voluntary" (DCLG not accepting then that revocation was caught by the SEA Regulations).
Here is the link to the consultation in respect of the East of England Plan (plus saved structure plan policies). This is the only consultation I could find on the DCLG website today but i assume they are all being posted now. Not surprisingly there is little difference in the conclusions. But they must be keen to get on with the exercise, to be kicking off this week with a consultation ending on 20 September!
