The hon. Gentleman is right in one regard: tariffs are important—in some areas, very important—but the non-tariff barriers, as I said earlier, may be more significant. We are already seeing skilled labour leave and not come back. We are already hearing that our universities, which he mentioned, are now worried because their academic working together with Europe is no longer there. The relative advantage of an English-speaking country with access to the EU market was there for all to see. Some people now wish to rip that up.
Every single Brexit model is bad. Investment is likely to fall, trade will most certainly be reduced, barriers will be erected, people will be poorer and productivity will be stifled. On that basis, we need to think, and think again—and quickly. As I see it today, and I will paraphrase the Prime Minister’s words from another constitutional debate: there is no positive case for Brexit, now is not the time for Brexit, and frankly, Brexit must be taken off the table.
