Restoration and Renewal of the Palace of Westminster

The Leader of the House has acknowledged that he is not an expert, and that most of us in this House are not experts on running major projects. The original intention of the Act of Parliament passed by this House, which has been unpicked in private in the Commissions, was that an expert body, the Sponsor Body, would be created to deliver that expertise. That body has now been abolished. He says that it has been brought in-house, but many people have left it. Can he be very precise with the House about exactly what will replace it, and where he thinks that expertise will come from in the Commissions, which in both Houses do not have the inbuilt expertise to deliver this project?
