I finally got a reply from my MP attaching a statement from Lord Adonis (for Gods sake!). It just restated the governments position.  Basically, if a car is used in another EU country and brought back into the UK then it must not be used abroad again within 6 months. Literally, if you made 2 booze cruises to Calais then you could be told that you should re-register your car in France. The obvious contradiction that the vehicle spends the other 364 days of the year in the UK does not compute with moron.gov.uk. Good old Labour with their 3000 new offences. How many have you commited today?
