Also most holding procedures in the Europe use NDBs as the holding
fix. (there are currently NO operationally published GPS approaches
in the UK, and the CAA and even JAA are tending to be somewhat wary of
implementing GPS procedures for instrument approaches.)

Is there a single rationale for this wariness? The obviously compelling
reason is that other nations would be reluctant to throw the future of their
air navigation into the hands of a system controlled by the US military -
we're allies now, but alliances change within the lifespan of an
aeronautical system. Or is there something more mundane: the incremental
cost causing slow adoption, or the decision to put more INS systems into
European planes before GPS came along, or roll out MLS faster than the US,
or what?
