The answer is as soon as possible, once this Bill has passed. I am looking forward to working with the hon. Lady in Committee to make sure that we can work through this as quickly as possible. Clearly, work will be done in consultation and conversation with the LGA and local councils to ensure that we can get comprehensive guidance in place. That is how we have been working over the past 14 months with local authorities on the other grant schemes.
Let me briefly cover a couple of quick points. The hon. Member for Manchester, Withington (Jeff Smith) asked whether there will be a blanket ban on MCCs. I can absolutely confirm that there is no blanket ban. On airports, it is a core principle of the business rates system that a material change of circumstances should be used between rate revaluations, so the drop in demand for airports in light of the pandemic is exactly the sort of market-wide economic change affecting property values that can and should only be considered at revaluation. We have been supporting airports with their fixed costs over the past year from the airport and ground operations support scheme. In his recent Budget, the Chancellor announced a further six months of support up to the equivalent of their business rates liability for the first half of the 2021-22 financial year, subject to certain conditions, and a cap per claimant of £4 million.
