Even within the two camps there are divisions: for Remain, Theresa May is much less apocalyptic on the economic consequences than George Osborne, while for Leave Michael Gove, with his “Albanian option”, sees a far more radical change than, say, than Boris Johnson.

But with so much depending, frankly, on economic conjecture, a voter might reasonably ask about what is actually going to happen – not to household incomes in 2030, but on June 24 2016, or soon thereafter, in the event that Britain votes to leave the European Union?

That should be a simple question to answer. No need to search for the missing variable in each side’s macroeconomic modelling or ponder contrasting Franco-German appetites for Eurozone integration. Just a simple case of who does what, and when. We know what happens after a General Election, after all – but four entirely separate conversations I’ve had this week have made it clear that this most basic of voter requests is all but impossible to fulfil.
