Peter272 - the role of Incendiarist (Parliamentary) was placed on a 'capability holiday' some years ago, with the aspiration that the position would be filled in due course via a PFI.
Unfortunately, the contractual details have taken longer to negotiate than anticipated, with disputes between the Parliamentary Authorities, the MoD and the preferred bidder over who, exactly, bears the risk in this arrangement.
Wyler - splendid idea.
