6.1 The government agrees with the Committee’s recommendation. Target implementation date: Autumn 2022 6.2 The Levelling Up White Paper sets out twelve missions that support levelling up outcomes. Missions are a tool to break down silos and encourage collaboration across the public, private and voluntary sectors. To ensure missions deliver these benefits the department have implemented a new architecture across central government to support delivery. The ‘mission architecture’ provides clear accountability through named individuals taking responsibility for progress and puts in place structures designed to smooth interdepartmental cooperation on a mission-by-mission basis. This includes the Levelling Up Cabinet Sub-Committee, which has been established to embed levelling up across central government policy design and delivery. Once these arrangements have been confirmed with new ministers, the department and HM Treasury will write to the Committee separately with further details.
