However, the proposers of innovations—particularly innovations that impact on the incomes of and services for working families—have a responsibility to demonstrate and provide evidence for the benefits that are claimed, to explain the consequences for policy and for infrastructure, to explain costs and to reduce or eliminate concerns about likely results. At some future date, we might inquire more broadly into the consequences of Mr Sheridan's programme for working families, but it is obvious that we are not going to hear the appropriate indications from the proposer today.I want to outline some reasons why I will not support Mr Sheridan's motion and why I urge other members to reject it.
