In addition to what has been said, in particular by 172driver, I suggest that he buy Trevor Thom's (or whatever is being used these days) and the PPL Confuser, then pop down to Jerez for a few days, or over a couple of weekends, and get the theory out of the way with B. Mellor at Fly in Spain. We are talking self-study here but there's nothing intrinsically difficult about PPL theory.
Then he can take a bit of a holiday and complete the flying part either with Fly in Spain (not just Cuatro Vientos, but the whole of Madrid is a dump anyway so I'm sure he'll appreciate the idea of spending time elsewhere), or if rmcb is correct, it appears that he might be able to negotiate with any other JAA examiner to do the skills test for him. I would run this through both the CAA and, if you can get hold of them, the Spanish DGAC.
Whatever he does, I would steer well clear of LECU if I were him.
