DESCRIPTION:We establish non-unirational versions of Hilbert I
 rreducibility for all Hilbert modular surfaces whi
 ch are of K3 type. The proof uses the multiple fib
 ration method in combination with Shimura theory. 
 As an application we prove new instances of the re
 gular Inverse Galois Problem for the simple groups
  PSL(2\,p^2) subject to congruence conditions on p
