Oxford Street in London to become pedestrian-only zone

• Oxford Street in London will be pedestrianised, banning cars from the busiest stretch.
• The plan, initiated by Mayor Sadiq Khan in 2016, faces numerous setbacks before its implementation.
• The pedestrianisation aims to make cities greener, less congested, and more inviting.
• Big brands are investing in flagship stores on Oxford Street as part of the initiative.
• The transformation is seen as a case study for urban development in Europe.
