That's nonsense, Car Giant already acknowledge they will be leaving the site and hope to be part of the development, but only the person chosen by the GLA or rather Boris, will be able to build it. The developers Cargiant have chosen to work with have never worked on a project bigger than 900 flats, Old Oak would be 25,000. They aren't exactly pushing the boat out in terms of effort. Whereas we've chosen one of the biggest developers and are backed by some very rich industrialists.
Beard going is nothing to do with the stadium.
