Actually, to be fair to the UK government (just for once), they were forced to comply with existing EU law. It was possible until Dec 31st last year to import an aircraft of over 8 tonnes into the EU and gain "free circulation," by simply making your first point of landing in the EU in England, and registering the importation in an appropriate way - irrespective of whether the aircraft was private or commercial. EU countries objected, and UK relented.
End of story.....unless some clever German lawyer gets his teeth into this area of EU law, and again redefines the word "commercial" - as he recently did to the glee of many of us lucky M reg drivers. Way to go!
