Badger Cull

I am grateful to the hon. Lady for giving way and apologise for missing her opening remarks. She is right that perturbation is a key issue, but she is not right to say that the Independent Scientific Group trials were based on hard boundaries. The fact is that the areas had to be exactly 100 sq km, otherwise they would not have been comparable. The boundaries therefore had to be accepted largely as they were. The difference with the current culls is that they do not have a maximum size, so the zone can be chosen to meet whatever good hard boundaries can be found and steps can be taken to minimise perturbation. The net benefit should therefore be much higher than was achieved in the ISG trials.
