In our report of 8 January 2021, we recommended that the Department should clearly set out what activities it intended to complete and by when to achieve its revised targets. As part of this, we recommended that it set out the final dates by which key milestones must be reached in order to meet those targets and publish yearly updates on progress thereafter.16 In response, the Department told us that the overall programme delivery profile will be incorporated into the Programme Business Case which was due to be submitted for approval in Summer 2021 and that it would publish its progress against the programme’s milestones regularly.17 More recently, in its letter to us ahead of our evidence session, it told us that the full programme business case was now undergoing Treasury approvals and once the business case has been approved, it will provide further detail on its overall delivery projections for the programme.18
