I have been a strong supporter of freedom of movement for the whole of my adult life. I remember as a teenager being at the border posts that used to exist in our common European home. I have a stamp on a passport from France. I remember having to show my passport to cross the rivers and roads of our continent. One of the greatest gifts that the European Union gave us was to remove those borders and to remove those border posts, to remove that need to demonstrate that we were unable to move from one piece of turf to another.
