'Freedom of Movement' would have been considerably less 'open to abuse' during our membership of the EU if successive UK governments had not chosen to ignore the EU's own system of controls, and enacted the recording/registration of arriving EU citizens, monitoring them during their stay, and ensuring that any who, after three months, did not have accommodation and employment, were sent back whence they came.

Uncontrolled immigration from the EU has not been the fault of the EU, but of our own governments. The means of controlling EU immigrants have always been there, but our own governments have chosen not to enact them.
