It's true alright! Carill made the decision a couple of months back. Both flying schools could keep going from Southampton, but could only keep their aircraft on the North Apron for short periods, which would make things a little difficult operationally!
I have flown into Lee and it is an excellent place! and should if possible be used more for GA.
I believe the police own the site? The police islander and coastguard rescue helicopter IJ are kept there, so security and access is strictly controlled.
Am hoping to find out more in the next week or so.
