The London Plan is the statutory spatial development strategy for the Greater London area in the United Kingdom that is written by the Mayor of London and published by the Greater London Authority. It is updated from time to time.

The Sutton Link was a proposed new tram line in South London, between Colliers Wood via St Helier to Sutton. Proposed since the early 2000s, consultations on the proposed route took place in the late 2010s. A preferred route was announced in February 2020. Financial issues caused by the COVID-19 pandemic led Transport for London to put the project on hold in July 2020. Despite being identified in the London Plan, the project was cancelled in 2023, due to a "weak business case" and lack of funding.
