During the last few years of public and parliamentary debate around Brexit, there has been much discussion of a no-deal scenario and the United Kingdom simply leaving the European Union ‘on World Trade Organization (WTO) terms’ or ‘under WTO rules’.

In reality, this phraseology is confusing. At its most basic, it is a reference to the nature of the future trading relationship between the UK and the EU absent any agreement on such a relationship. But, in practice, the ideas that underlie the simple expression are much more complex and nuanced. What exactly are ‘WTO terms’ and to what sort of 'trade' do they apply?

Peter Ungphakorn, who spent 18 years of his career in the WTO Secretariat, tries to clarify some of the confusion in this area, explaining the nature of WTO agreements and attempting to unpack their relevance within the context of Brexit.

The talk covers:

What is the WTO?

To what does the phrase ‘WTO terms' refer in relation to goods and services?

Is UK-EU trade already governed by WTO rules?

Understanding the MFN (most favoured nation) principle and its critical importance.

A ‘no-deal Brexit’: what can and can’t be done under WTO rules?

Why are some hard Brexiteers so interested in Article 24 of GATT?
