Under LU rules a random or "for cause" D&A test is always supervised
by a senior grade, I'm presuming the LU system was adopted by TFL
(which took over many civil service personnel who were previously not
under such draconian rules!). In Kiley's case who would the
supervising senior person be?

As an aside, a friend of mine absorbed into TFL Streets from the DoT
turned down a staff pass for a number of years to remain on civil
service conditions and thus still be able to have a drink at lunchtime
(*not* to get drunk I might add!).
