I congratulate my hon. Friend on his important Bill. I have seen for myself the horrendous spread of ragwort along verges next to agricultural land on which horses graze. It is especially insidious because the weed can be harvested with the hay and is equally poisonous when it is dried out. Can he confirm that people who pull up ragwort should wear gloves, because it can be damaging to the human liver to pull it up with bare hands for prolonged periods?
