This is definitely good news. Paul Myners is to chair the Personal Accounts Delivery Authority. This is, if I understand the process correctly, the body that will get the PA scheme started before handing it over to the appointed trustees. See this bit from Professional Pensions.
I say it's good news as Myners is definitely a decent bloke, will listen to the views of the labour movement, and is a proponent of shareholder engagement. All potentially rather positive. The TUC like it, understandably.
