Add to this the fact that successive British Governments believe every word that spouts from Brussels so you must allow a fair tendering for vehicle contracts for the police/ambulance/fire/post office/local government just as they do in france (how many non french police cars do you see?) and germany (how many non german ambulances do you see?) etc etc etc
As the French say...keep the country's public money IN THE COUNTRY!!! Why should anyone else have it!!!
