I lived in Gran Canaria for 6 months and although I drove legally, numerous people drove on provisional licences, borrowed other peoples etc. One locally bar owner drank a bottle of scotch was driving home when the local police stopped him, they asked him to get out of the car, he said he couldn't because he was too drunk, so they drove him home!
I got pulled a couple of times by the police routinely and although they look at your licence I don't think they knew what they were looking for and I doubt that they would have access to the DVLA, but you never know.
