My right hon. Friend is exactly right. We do not have to be expert builders to see that this is going to cost money and it is going to take time. I see no alternative to both Houses having to move out for a period of time, as yet undetermined.
I also say in response to my right hon. Friend that this shows the critical role of the Commons Finance Committee, the Parliamentary Works Estimates Commission, chaired so ably by my right hon. Friend the Member for Newcastle upon Tyne East (Mr Brown), and the Public Accounts Committee, which has done such excellent work. Members of the PAC are here today and are very knowledgeable and skilled at exactly that sort of line by line scrutiny. We would need that whoever was commissioning the works—whether it was the Sponsor Body, and both Committees have paid close attention to the current structure, or any future structure.
