Government of Wales Bill

The Secretary of State is right to say that, throughout, the Liberal Democrats have sought to improve the Bill, rather than to block it, and it is in that context that we have had the dialogue. In the context of what he is saying now, will he accept and register the fact that we still feel unease because we cannot be guaranteed that any future Secretary of States for Wales will necessarily be sympathetic to the referendum? How can he feel confident that the arrangement that he has constructively laid out will nevertheless not offer an opportunity for, for example, an anti-devolutionary Conservative Secretary of State for Wales to prevent the referendum from taking place, given that he is not giving us a time-limited period by which the Secretary of State must necessarily have laid the referendum before the House?
