It is worth remembering that it is but a few years since the main users of RAF Uxbridge moved across the street to Northolt. The Central Band and Music Services, The QCS, AHB(RAF) and a number of other units would need to be found homes.
Northolt has a particular attraction for the great and the good and I can't see them letting the place go easily. Mind you, when the Greens get into power and the armed forces are replaced by whatever, perhaps we won't need Northolt or anywhere else for that matter.
