Leave and Remain are running neck and neck in online polls, with Remain ahead in surveys conducted by telephone. Both campaigns have faced sharp criticism – Remain for relying on Project Fear to cower the electorate into submission, Leave for failing to paint a clear picture of how Britain would function outside the EU.

Nowhere is this lack of precision more evident than in the economic sphere – the area where Remain scores over Leave.

TCW has decided to help. We are inviting our readers to spell out – in no more than 500 words – the best trade and economic arrangements for a Britain independent of the EU. Would we remain in the single market? Would we still be bound by the EU’s founding principle of free movement of people? How would we protect the interests of the City of London? How would we control immigration? Would we be better off outside the EU and why? How should we go about finalising the terms of our divorce from Brussels if we vote to leave?

These are some of the key questions that have yet to be answered definitively by the Leave side.

Some campaigners argue that by spelling out a detailed blueprint for a post-Brexit Britain we are creating a hostage to fortune. We would give Remain a target to shoot at and an opportunity to demolish the Leave case.

But is this right?

TCW invites its regular writers and all those who comment on the site or read it to join the debate and enter our competition. Ideally, we would like to publish the winners under their real names but anonymous entries will be considered.
