Oxford Street, one of the world's busiest shopping streets, will be pedestrianised from 26 October following London Mayor Sadiq Khan's announcement. Vehicles will be banned from almost one kilometre of the stretch between Orchard Street and Great Portland Street, with the Mayor citing strong support from Londoners and businesses and promising the move will boost regeneration and economic growth in the capital.

However, the plan remains controversial, with Westminster Council describing a "long list of unanswered questions" about how it will operate. Critics, including the Marylebone Association, have raised serious concerns about access, air pollution, street cleaning, and public safety, warning that traffic will be pushed onto surrounding small streets and that the car-free zone may become vulnerable to gang activity and shoplifting. The street currently receives around half a million visitors daily, and Khan had to obtain Government permission to establish a Mayoral Development Corporation to bypass local opposition, having failed in a previous pedestrianisation attempt in 2018.
