Not the same article, but similar, on sheep meat trade.
https://britishmeatindustry.org/industry/imports-exports/sheepmeat/UK exports about a third - 95/6 % the EU, mainly to France (45 - 55%) and some to Germany (10% +) - and imports a third (mainly from NZ (70%), Oz (15%) and the EU (10%). NZ and Oz have a deal with the EU with tariff-free quotas.
For Sunny as we worth both wondering:
Exports largely aim to address imbalances in demand for different cuts and the higher supply of sheep meat at certain times of year. Also, additional markets have had to be found to take items for which there is no or minimal demand on the domestic market, including offal and skins.
The UK exports mainly carcasses, plus offal, 2015 valued at £302m (which was lower than usual due to weak euro at the time). It imports mainly bone-in cuts.
Now to some of my questions on this:
There is a lot of talk around at the moment about Free Trade Agreements (FTAs), as if they are automatically a good thing. However, there does need to be caution as we do not want the UK flooded with meat from other countries that is either not as well produced as UK meat or simply swamps the market with the concomitant negative impact on British farmers and meat processors. Now Liam Fox is "mulling" over the idea of slashing UK tariffs - which would lead to the risk of market flooding, negatively affecting domestic producers.
Outside of a deal WTO tariffs would be around 50% depending on the product classification, affecting the competitivity of UK exports (although partially mitigated by the weak pound).
Add to that all the hassle and cost of certification, customs, transport, a potential lack of subsidies (as it's not clear where the gov would get the money from)...
