The Europeans will slap tariffs on British goods so that they don't take jobs away from Europeans.
My phones, until quite recent years, were made in Canada.
The principle of non-discrimination means that WTO members must not treat any member less advantageously than any other: grant one country preferential treatment, and the same must be done for everyone else.
There are exceptions for regional free trade areas and customs unions like the EU, but the principle implies that, outside of these, the tariff that applies to the ‘most-favoured nation’ (MFN) must similarly apply to all.
In practice, this should prevent the EU introducing tariffs on the UK which would discriminate against us or punish us, or the UK introducing similar tariffs on the EU.

UK will agree tariff-free trade deal with EU, minister claims
The European Union will agree a tariff-free trade deal with the UK – and it will not run into the
same difficulties faced by the troubled Canadian pact, a cabinet minister has insisted.
Transport Secretary
Chris Grayling said the amount of trade done between the UK and EU puts it in a different category to the Canadian deal, which has been blocked by the Belgian regional parliament in Wallonia.
The prominent Brexit-backer played down the prospect of the Walloons forming
a similar obstacle to the UK's negotiations with the EU because of the amount of produce their farmers sell to Britain.

Theresa May: Government not muddled over Brexit
BBC News
8 January 2017
The Prime Minister on Sky News's Sophy Ridge on Sunday this morning
Prime Minister Theresa May has said the government's thinking on Brexit "isn't muddled at all".
Her comments on Sky News come after the UK's former ambassador to the EU, Sir Ivan Rogers, criticised ministers' approach to negotiations.
Mrs May said the government's priority was to get the "best possible deal" and that she would set out more detail on her aims "in the coming weeks".
Brexit talks with the EU are expected to begin as early as April.
Mrs May said it was not possible for the UK to hold on to "bits" of membership after leaving the EU.
There has been much debate in recent weeks about the nature of Brexit, and whether controls on the movement of EU citizens will mean the UK leaves the European single market and customs union.
The government has also come under pressure to reveal more of its plan.
Sir Ivan stepped down from his ambassador role on Tuesday, criticising "muddled thinking" among ministers. He has been replaced by Brexiteer Sir Tim Barrow.
Mrs May told Sky News's Sophy Ridge on Sunday: "Anybody who looks at this question of free movement and trade as a sort of zero-sum game is approaching it in the wrong way.
"I'm ambitious for what we can get for the UK in terms of our relationship with the European Union because I also think that's going to be good for the European Union.
"Our thinking on this isn't muddled at all."
