I don't think anybody's suggesting that results have been made up. What the campaigners have said all along is that absence of evidence is not evidence of absence, and what I suggested in the Petitions Committee, as I said, was, in consultation with campaigners, let's decide on a set of parameters that can be followed, including testing—different testing, perhaps—at depth, in order to reach a conclusion that people agree on at the outset. There is a clear lack of confidence, rather than a lack of trust in individual scientists. It's building that confidence that we need to do.
