Wishful thinking, perhaps ...

... but hope for UK expats in Spain (of which I am a sort of country member).  Bloomberg reports:

... at an EU summit in Malta earlier in February, May and Rajoy were said to have struck an understanding.

The pair agreed they wanted to reach an early agreement on reciprocal residency rights for their citizens, according to British officials. May’s team in London believe Rajoy could also make a powerful ally during complex trade negotiations that will form part of Brexit talks, one official said.

Almost 18 million Britons, a number equivalent to almost a third of the U.K. population, visited Spain last year. Spanish companies also export far more to the U.K. than the other way around.

 But there's a fly in the ointment:  Gibraltar.  Rajoy will seek joint sovereignty and May will inevitably resist.
