I'd like you to elaborate why you think the NFU and the NSA are responsible for the Government's announcements?
Without defending the tone of the post you refer to:
The NFU President was the only person to sit on both of Mr Dimbleby's advisory panels.
His report called for less livestock and for methane masks to be fitted to those we don't get rid of.
His report totally ignored the food chain - the place where all of the environmental damage is caused - and laid the blame squarely with the primary producer.
All of this warmly welcomed by the NFU President.
The NFU are, to answer your question, responsible for Government announcements on farming being to blame, because the NFU advised the Government that it is thus.
