They probably didn't do so because your link is just to a previous thread of yours and the Pdf attached is your opinion that all area based ELMS should be paid solely to permanent pasture and that arable land doesn't need public money. You have admitted on a previous thread that you are not even a farmer, and refer to the farmers posting on here as muppets who bitch and whine so raises suspicions as to why you are even on this forum. Defra know our contact details so quite easy to get our opinion without posting on TFF which most farmers I know haven't even heard of.
And as I explained in the OP on that thread, I only shared our submission to get the ball rolling. Nobody wanted to play, because nobody wanted to actually do positive stuff.
Due to the internet no agricultural policy has had more chance for input. Blaming Defra is a p!ss poor excuse.
