Leaving the EU
The Treaty on European Union provides for a Member State to leave the EU, either on the basis of a negotiated withdrawal agreement or without one. If the UK were to leave the EU following a referendum, it is likely that the Government would negotiate an agreement with the EU, which would probably contain transitional arrangements as well as provide for the UK’s long-term future relations with the EU. There is no precedent for such an agreement, but it would in all likelihood come at the end of complex and lengthy negotiations.
