I think there have been issues with farming, food production and manufacturing, and sales for decades.
Hence many farmers listening to the Brexit promises. There was existing tension.
The aim should be to make UK farming pay better for those actually farming. It should never have become a tax vehicle for the wealthy.
I don't know how those structural problems could be picked apart. The previous government certainly couldn't or wouldn't get a handle on it. And it couldn't compete as an issue against the desire for trade agreements at any cost. That won't be any better with Trump 2.0.
Labour will certainly not prioritise ithose issues yet - we've got public buildings falling down, prisons overflowing, 14.3 million children in relative poverty, NHS productivity issues etc etc.
So I have some sympathy. But rather than blocking Parliament Square and accepting the Reform/Tory wellie wearing cosplaying I think they should be pushing for raising the cap or introducing tapers. Aim for meaningful changes to the policy rather than a u-turn.
Just my uneducated thoughts on the issue. My grandad was the 9th boy - he was never considered for any part of his family farm!
