That is a good point. The debate tends to revolve around tariffs rather than non-tariff barriers, which are often the biggest impediments to trade. However, as has been pointed out by Members on both sides of the House, since 2010 an increasing number of non-tariff barriers have been applied by the G20 countries. It is not acceptable for the richest countries in the world to say, “We have done very well out of free trade”, and then pull up the drawbridge behind them. If we ourselves have benefited from free trade, it is our moral duty to ensure that generations after us, both at home and internationally, benefit from it as well.
