And the last point, Minister, is around vaccination. Where vaccination is available, it has a role to play, clearly, in TB eradication, but it can only be used to prevent and not to cure the disease. Field trials with cattle TB vaccination, as you've already outlined, are under way, and you are hoping an effective vaccine will be available by 2025, so my question is: how confident are you we can achieve this goal, given the low number of farms that are currently participating in the trials?

And my final point is this: by ruling out other measures such as controlling the disease within the wildlife population, is the Minister accepting, therefore, that the Government is content with keeping the situation as static as it is currently for at least another three or four years, which won't reduce the emotional or financial burden on farmers one bit, or reduce the prevalence of the disease to the same extent we've seen in other countries? And my final point as well is the found-dead survey, in my opinion, is ineffective and rather ad hoc and doesn't teach us anything about this disease at all. Diolch yn fawr.
