Halton
From what I remember the decision to close Halton has already been screwed up once, when the Technical training school moving to Cosford in the early/ mid 90s. As far as I'm aware the plan was to shut Halton until at almost the last minute it turned out that the original terms of the purchase of the land from the Rothschild's means that MoD has to return the land back to its original condition and then have to sell it back to the family for £1.
It might just be an old wives tale though but someone must know if this is definitely the case.
