RAF St Mawgan is not closing. The airfield, however, will be transferred to the Council from DLA on 1 December as scheduled.
I cannot envisage a last minute change of decision by the MOD. As was mentioned in the MOD press release, the RAF personnel currently employed at St Mawgan have other posts to fill. There have already been extensions granted to the Council and RAF personnel have had their careers / personal lives etc put on hold more than once already. Bear in mind that its not just those in post at St Mawgan that are affected, it has a knock on effect throughout the branch.
