This document airports-nps-new-runway-capacity-and-infrastructure-at-airports-in-the-south-east-of-england-web-version contains the justification of my assertion that Luton Borough Council is the Planning Authority who decides on proposals for increases in runway capacity at London Luton Airport (if they were put forward by London Luton Airport Limited) and not the Secretary of State at the Department for Transport. It’s a long read. Nevertheless, if you want to effectively participate in our modern democracy it is required reading. Please feel free to disagree with my assertion but please site a documentary source of any justification for your disagreement.
