■ Retain the NPPF and avoid a further radical overhaul of the planning system.

■ More coordination on strategic issues either by strengthening the duty to cooperate or by providing a “larger than local” tier of planning. The role may be filled by stronger and better-funded Local Enterprise Partnerships, County Councils or “city region” planning boards.

■ To address London’s unmet housing needs, more formal structures of cooperation with neighbouring authorities are required. Garden Cities are also potentially part of the solution but an identifiable process is needed to bring forward land for these new settlements.

■ Stronger measures to encourage the adoption of up-to-date plans. These might include: a statutory requirement to produce an up-to-date plan within a given timeframe; an enhanced new homes bonus where homes are delivered based on an up-to-date plan; and where there is no up-to-date plan, an assumption that there is no five-year land supply (the Welsh system).

■ Clear requirement for a local plan to be adopted prior to any neighbourhood plan to ensure a proper chain of conformity.

■ Single approach to the calculation of five-year housing land supply to provide greater clarity and to help ensure sufficient sites are allocated for residential development.
