I can keep british agriculture in an iron fist of control without spending a penny. In fact I could charge you for it, like DT is going to charge the Mexicans.
I would introduce a farming licence which is like a driving licence. You would have to do exams to get it, and pay for the lessons and test just like spraying. My inspectors would visit you repeatedly, and charge for their visits. DEFRA would be self financing like VOSA so it is in the inspectors interest to find misdemeanors. If they find anything wrong they suspend your licence which means there won't be any buyers for your output. Buyers won't be able to buy from unlicensed businesses. I'm toying with increasing the scope of SMR's which means I could take you to court and get you fined, with costs, of course.
I'm glad to say I'm 70 this year with no successor so I will be well out of it.
Bring it on,it would cull the ones not fit to do the job and leave competent ones,however they would have to pay for more expensive food as if I have to go to all that bother I would do it in another industry which values my commitment and has remuneration to match.
A good example is truck drivers,since bringing in the driver CPC it is harder to employ one and more costly.
