The thing about controlling immigration aka the power to decide who can and can't live in the UK panders to the whims of the powers that be to determine who does/doesn't meet the criteria they choose to apply.

There are already issues with people in the UK in relationships outside the UK, even married couples, as the policies favour people who are higher earners, based on an arbitrary amount? There has been no guarantee that this will not apply to anyone in a partnership with someone form the EU - now and in the future.

What gives any government the right to dictate who an individual is allowed to live together in a relationship with - I am not talking about marriages of convenience but real loving relationships.
