The free movement of goods, services, capital and persons within the EU are the famous “four freedoms” set out in the Treaty of Rome.

The same principles are now extended under the "internal market” rules introduced by the Single European Act.

The four freedoms are strengthened in the Lisbon Treaty, also by a special Protocol 27.
