Pedestrianisation of Oxford Street: pledges, trade and trade-offs

Major changes to the capital's most famous shopping street look to be on their way, though how closely they match Sadiq Khan's manifesto promise remains to be seen

Sadiq Khan is not the first London mayor to pledge to transform Oxford Street from a clogged, smogged motor highway lined with shops into a clean, green avenue of retail walking therapy, but he just might be the last. That is because he just might do it - or, at least, provide the political drive to help others to take big strides in that direction.

If it happens it will be, in part, because Khan will have brought the same energy and know-how to bear on the problems threatening one of the most famous shopping streets in the world that characterised his capture of City Hall. It will also be because wider circumstances have rendered continuing inaction unacceptable.

Work with Westminster Council, local businesses, Transport for London and taxis to pedestrianise Oxford Street. I will start by bringing back car-free days and possibly weekends before moving towards full pedestrianisation. Our eventual ambition should be to turn one of the world's most polluted streets into one of the world's finest public spaces - a tree-lined avenue from Tottenham Court Road to Marble Arch.
