The Greater London Authority (GLA) was established in 2000 to provide city-wide strategic government for London. The Mayor is responsible for strategic planning in London and has a statutory duty to produce a Spatial Development Strategy (The London Plan) and keep it under review. This strategy and associated documents are available through the Mayor's website.

The Mayor is a statutory consultee for planning applications which are strategically important to London. These are known as referable planning applications and are defined by the Mayor of London Order 2008.

The Mayor is required to provide a statement of compliance with the London Plan within six weeks. The Greater London Authority (GLA) consults TfL on all referable planning applications. TfL's Borough Planning team then provides multi-modal transport comments on behalf of TfL for the aforementioned statement.
