Very simple, the next door site is the Long Marston Depot, in Startford District, which now makes the Long Marston Depot alternative in Stratford District much more likely, which could knock out the alternative Gaydon site in Stratford District at EIP. The Stratford local plan is out of date even before it reaches examination.
Expect an application for Long Marston Depot to be banged in, as prematurity now much less of an issue.
