Public Service Pensions Bill

I thank the Minister for giving way. He says that the Treasury does not recognise the figures in Michael Johnson’s helpful report, mentioned by my noble friend Lord Flight. Could he say what figures it does recognise because, clearly, the proposals for the single tier pension and the impact on contracted-out contributions came after the development of the public sector pensions and after the OBR report? There has to be a figure, given that he does not recognise that quoted by my noble friend, so what figure do the Government estimate it to be?
