Ahaha, hilarious! WTO insists that ‘most-favoured nation’ terms are applied to all other country trade not covered by a free trade agreement. Thus, we would be subject to EU import tariffs under WTO rules. I'm sorry to say you are simply wrong. Have a look at this from the CBI for example, all outlined there for you, or are they also making bold statements on things they don't understand! You are a riot!
Access to European markets on WTO terms would hit British exporters and importers with tariffs
Under the WTO framework, the key principle of non-discrimination requires members not to treat any trading partner less advantageously than any other, unless covered by a free trade agreement or laws giving developing countries preferential access.
For goods, this means that tariffs applied to the ‘most-favoured nation’ (MFN) must apply to all other countries too. The EU could therefore not apply discriminatory or punitive tariffs after a UK exit above or below its MFN levels. As Exhibit 62 shows, the EU’s average MFN tariffs have fallen consistently over time, and so the WTO framework would prevent the tariffs imposed on the UK from being as high as they would have been 20 or even 10 years ago. Nevertheless, new tariffs of economic significance would still be imposed on around 90% by value of the UK’s goods exports to the EU, causing most UK exporters to become less price competitive than their EU competitors or companies from countries with which the EU has signed FTAs.
If the UK – having negotiated in the WTO as part of the EU – were to inherit the EU’s common external tariffs as a starting point for its own tariffs, companies importing from the EU would be hurt as import tariffs would rise from the zero level for intra-EU trade to the level of the EU’s external tariffs. The implications of a move to an MFN trading arrangement for exporters and domestic consumers would vary considerably by sector. For instance the UK runs a £2.9bn trade surplus on liquefied natural gas that would be hit by a 4.1% tariff.
Trade in services between the UK and EU would also be governed under a WTO framework, the WTO General Agreement on Trade in Services (GATS). Under this agreement, all WTO members again have to respect the principle of non-discrimination, and varying levels of binding liberalisation commitments are made by WTO members in individual services sectors. As a ‘stand-alone’ WTO member, the UK would be faced with the same level of access to the EU services market as all other WTO members in line with the EU’s GATS commitments – a much lower degree of access to the free movement of services which is a central facet of the Single Market enshrined in the EU Treaties.
As tariffs and quotas have become less prevalent barriers to global trade, non-tariff barriers have become increasingly significant (see Exhibit 63). For example, a direct consequence of leaving and not preserving a common regulatory agenda with the EU would be that regulatory divergence would creep in over time and British businesses could face new non-tariff barriers that would harm trade with the EU.
