The crucial EU issue for the UK is not whether to leave or stay in the Union, but what Britain can do to achieve the EU it most wants. Threats to leave are counter-productive and reinforce an image of Britain as a grumpy old man best left alone and placated only when essential. Success will require a positive approach and cordial relations with those other member states likely to share those particular goals. Grandiloquent claims of British 'leadership' are equally unhelpful. The UK needs a strategic plan, to which this report is intended to contribute, and rather more effective diplomacy.
