Brexit, Ireland and the World Trade Organization: possible policy options for a future UK-Australia agrifood trade agreement Article Accepted Version Swinbank, A. (2018) Brexit, Ireland and the World Trade Organization: possible policy options for a future UK-Australia agrifood trade agreement. Abstract Prior to the United Kingdom's accession to the then European Economic Community (EEC), in 1973, Australia was a significant supplier of Britain's food. Membership of the EU resulted in trade diversion, closing the British market to Australian sugar for example. This paper questions whether the UK's exit from the EU ("Brexit") might usher in a new agri-food trade regime, restoring Australian farmers' access to the British market, or whether other opposing political economy considerations might prevail. Would the UK unilaterally adopt free trade? Can a comprehensive Free Trade Area (FTA) agreement between Australia and the UK, including agri-food products, be negotiated? Any new relationship will need to reflect the UK Government's stated preference for a frictionless border with EU27 (particularly on the island of Ireland), the WTO rule-book, and the interests of the UK's farm lobbies, as well as the UK's quest for 'free trade' with the wider international community. Summary at a glance: Trade in agricultural goods will be affected by Brexit (the UK's departure from the European Union) particularly over the UK's border with the Republic of Ireland, and potentially raises new trading possibilities for Australia. As we leave the European Union, we will negotiate a new, comprehensive, bold and ambitious free trade agreement with the EU, but we will also seize the exciting opportunities to strike deals with old friends and new partners. At this summit [the G20 in Hamburg], I held a number of meetings with other world leaders, all of whom made clear their strong desire to forge ambitious new bilateral trading relationships with the UK after Brexit. This included America, Japan, China and India. This morning, I welcomed Australian Prime Minister Turnbull to Downing Street, where he also reiterated his desire for a bold new trading relationship.
