He says: "What is particularly irritating is that we have the vaccines in the pipeline, but the commitment to really go in and test them is...not there".

Does the hon. Lady agree that farmers' voices are not unanimous on this issue? I have been contacted by Gloucestershire dairy farmers who support the vaccination model being developed by the Gloucestershire Wildlife Trust and, in the short term, the model of meticulous biosecurity that has been advanced successfully by Gloucestershire farmer Steve Jones , who has managed to contain bovine TB despite the fact that his farm is in the very centre of the bovine TB area.
