Constitutional Reform and Governance Bill

The hon. and learned Gentleman is arguing that clause 29 should not stand part of the Bill because the second-stage reform has not taken place. That would be a more credible argument if I felt that his party were champing at the bit to bring forward a second-stage reform, so let me simply ask him this. What commitment will the Conservative manifesto in this year's general election make to bringing through a wholly or largely elected second Chamber?
