Dangers of ragwort

I’VE JUST read John Spencer-Smith’s letter of August 11, regarding the danger to horses of the ever-increasing amount of ragwort.

One of my first jobs when I left school to work on a farm was removing ragwort, as in those days it was illegal to have it growing anywhere. However when the

set-aside scheme was introduced by the then government, the legal situation changed.

I wonder why? Was the government afraid of being sued by horse-owners for the death of their animals?
