asked the Secretary of State for the Environment what is the capital value of the hangars occupied on Bovingdon Airfield, Hertfordshire; and whether sufficient satisfactory storage exists as a replacement if the hangars are demolished.

I appreciate that it is not the practice to disclose valuations of property in the course of disposal. The hangars will not be demolished before June, 1973, at the earliest as there is a firm requirement for them until then for emergency stockpile storage. In the meantime, I will be reviewing whether there is any longer term need for this or alternative storage accommodation.
