§ Mr. John Smith
To ask the Secretary of State for Defence if he will publish all or part of the investment appraisal upon which he decided to roll forward the Harriers GR9 to RAF Cottesmore. 
§ Mr. Ingram
The decision that Harrier Air Depth maintenance support work should roll forward to RAF Cottesmore as the centre of gravity for logistic support, was taken following he results of a comprehensive Investment Appraisal (LA) which fully supported the decision by a clear margin over the other option. All key stakeholders within the Ministry of Defence, including the Chief Executive of Defence Aviation Repair Agency and the RAF were involved in the LA.
It is not appropriate to release the LA at this time, as it forms the first phase of other work to decide the location of centres of gravity for logistic support for other air platforms. This further work is still under ministerial consideration.
