Consent of a majority of the rest of the EU will be needed if there is to be a new UK-EU relationship

The only place in the EU where the issues that might arise from a UK renegotiation or withdrawal are being debated in any detail is in the UK itself. But any change in the relationship will have an impact on all member states. Tim Oliver and John Bruton write that it is therefore not simply about what Britain wants from its relationship with the EU, but also what the other 27 states would want, and whether these can be reconciled.
