Indeed, according to a report on public attitudes to the biological sciences and their oversight, “Having information and perceived hon- esty and openness are the two key consid- erations for the public in order for them to have trust in a system of controls and regu- lations about biological developments” (MORI, 1999b). In the past five years, there have been four major UK independent inquiries into the use of animals in biomedical research: a Select Committee in the House of Lords (2002); the Animal Procedures Committee (2003); the Nuffield Council on Bioethics (2005); and the Weatherall Committee (Weatherall et al, 2006), which specifi- cally examined the use of non-human pri- mates in scientific and medical research. has made important contributions to many such as the research councils.
