What does the British public think about human-animal hybrid embryos?

In the recent UK debate on the Human Fertilisation and Embryology Bill there have been conflicting claims about the extent of public support for, or opposition to, human-animal hybrids. Self-selecting polls tend to show opposition to hybrids. Representative sample polling shows spontaneous opposition but can elicit conditional approval of research combined with underlying unease. Public opinion is very finely divided with people generally opposed to this research unless it is likely to lead to medical advances.
