Park Royal Corporation

One item that should be coming up at the next Brent Executive is the proposal by Boris Johnson for a new Park Royal Corporation.  In principle, I can see this might be useful in certain ways, overcoming boundary issues, take a holistic look at issues such as the dismal air quality around Willesden Junction, the Hythe Road Path, or Mitre Bridge for example.  The trouble is I just don't trust Boris to deliver.  Given his reported run to Hillingdon, should that matter?
