It is not Parliament's role simply to rubber-stamp opinion polls. Opinion polls provide a snapshot of what a sample of the public say they feel about a given issue in response to specific questions at a particular time. Opinion polls can show public support for other controversial issues (on, for example, membership of the European Union, capital punishment or immigration). Law-making has to be conducted with care, especially where, as in this case, there are life-or-death issues involved. Parliament has to take into account the facts and to weigh the evidence. Legalisation of assisted suicide or euthanasia is a highly complex question, covering as it does a wide range of legal, medical, ethical and societal issues. Parliament has had the facts and the evidence presented to it. Moreover, some of the polls dealing with this subject are commissioned by campaigning groups and can feature misleading data and selective reporting of the results.
