Recommendation 4

EU Exit preparations involved more than 22,000 civil servants at the peak and have cost at least £4.4 billion. But there has been no serious attempt to reflect and capture lessons for other challenges that government faces. Every government department has been affected by preparations for EU Exit and this has put pressure on government’s ability to manage cross-government coordination and decision- making. Government has made changes to the way the process has been managed. The ministerial structure now consists of just two committees, one focused on operations and one focused on strategy, and it is clearer where to go for decisions. The Cabinet Office reports that it shares more information on preparations with departments. The key oversight functions, particularly the Transition Task Force and the Border and Protocol Delivery Group now all sit together within the Cabinet Office, which we are told has resulted in a closer working relationship. Government has recognised that other challenges it faces, such as the response to Covid-19, will also require cross-government working, working at pace, or working in new ways. The Cabinet Office feels that it has learnt a lot from EU Exit and put it into a practice via a process of continuous improvement. However, it has no plans to conduct a formal review of the preparations, relying on the National Audit Office’s work to identify lessons, rather than also choosing to do its own significant review of what it can learn for the future. Recommendation: The Cabinet Office should conduct a formal review, including seeking input from third parties (particularly the devolved administrations and Whitehall preparations for EU Exit 7 local government) and covering the whole period of preparations. This should be done early in 2021 when there’s a chance to see how plans have held up in reality post-transition. It should cover structures, communications and oversight—areas which can be applied to other cross-government undertakings.
