LLAL have not got a lease on the park but a licence. This was taken out in a secret deal in 2015 between the council and LLAL, which is their own limited company. The lease or sale for a £1 will come later.
The current planning applications for the park are a farce. LLAL have just put in amended applications last week after being condemned by the councils own planning inspector. The whole purpose of the applications is to put in a dual carriageway for a terminal 2 while LLAL are making out it is purely for a business park. The applications show a new Wigmore Park location complete with planting schemes to try and placate local residents while the consultation for airport expansion shows the same site as an airport car park with yet another Wigmore Park in the adjoining county of Hertfordshire.
