That's a good one. These top executive civil servants like to hide away in their little ivory towers. If they do something then, God forbid, they might be held responsible!
So, can't thinkg of a name and can't find one, but the address is
Rio House
Waterside Drive
Aztec West
Almondsbury
Bristol
BS32 4UD
The nbaem David Clarke springs to mind from way back, but maybe I'm wrong now.
