I think we might be. I will start with Clause 139, which amends Sections 62A and 62B of the Town and Country Planning Act 1990.
It allows the Secretary of State to set out in secondary legislation categories of applications that a local planning authority may be designated for, should their performance fall below the specified threshold. This will allow our existing approach to addressing any instances of underperformance, which currently applies only to major development, to be extended to include applications for non-major development. The existing designation approach has proved successful in speeding up decisions on major development since it was first announced in September 2012. By extending our approach to include non-major development, we are ensuring that all applicants can have confidence in the service to be provided.
We will keep under review the categories of applications on which performance will be assessed to ensure that they remain targeted at the most relevant aspects of the planning process. As the existing designation approach has proved, this measure has several benefits. It encourages improvement and gives applicants the choice of a better service in the very few cases of persistent underperformance. This approach has shown its effectiveness in tackling performance on major development, so it is only natural that we should now bring non-major development within its scope.
I now turn to the amendment moved by the noble Lord, Lord Palmer, on behalf of the noble Lord, Lord Tope, regarding applicants for planning permission having the choice to apply directly to the Mayor of London instead of the Secretary of State where a London borough is designated as poorly performing. I agree that it is essential that the Mayor of London plays an important part in strategic decisions affecting the capital, which is why the mayor already has power to call in for his own decision applications of potential strategic importance, for example where more than 150 dwellings are proposed.
I should highlight that if applications are submitted directly to the Secretary of State by applicants in areas that are designated as underperforming, Section 2A(1B) of the Town and Country Planning Act 1990 already provides for the Mayor of London to have the same call-in powers for applications that are of potential strategic importance. This ensures that the mayor can still take the final decision on applications of importance in London. I reassure noble Lords that we value the important role of the mayor in taking strategic decisions in London, and we are taking steps in this Bill to devolve more planning powers to the mayor. With that reassurance, I hope the noble Lord will withdraw his amendment.
