>>>I doubt if even DVLA or the police would tell you, due to data protection
Agreed, but the Data Protection Act also gives everyone the right to see what information is held about them, simply by making a request. The organisation holding that information must release it to the person to whom it relates but they cam make an administration fee (of no more than £10) for doing so. That's why it will cost Maisie a tenner for the information if she can't get it any other way.
