I once heard that there was a plan to move from London to Milton Keynes, this was also about 20+ years ago. Negotiations were at a quite advanced state when Brooklyn pulled the plug.
When work stopped on Chelmsford for a time, a few years ago now, the same brother that told me about MK said that if Chelmsford wasn't allowed to go forward there would be a revolt at London Bethel and Brooklyn would have to let the project continue, even if they sold it some years down the line. He was right as it turned out and I for one would not be surprised if they cash in on it in the future.
