You already had competitor agric giants (Canada, Australia, Brazil, US, Ukraine, NZ etc) Now you've made the giant farming industry of the EU your COMPETITOR.
Not yr partner. COMPETITOR.
So prepare for fewer farms, fewer farmers and fewer British-grown goods on shelves.
It wasn't until the 1984 Labour Govt (a decade later!) went totally free-market and deregulated everything that NZ's farming economy matured and boomed.
- You are already deregulated - more so than almost any other market economy.
- There is no 'poor 1985-like China' sitting out in the Atlantic waiting to take your ships.
- We (& the other giants) have a 3-decade headstart
