Last summer I launched my policy to pedestrianise Oxford Street, something I, and many other campaigners, have long called for.

Pedestrianising Oxford Street makes sense for a number of reasons: it would boost footfall and help local businesses; it would cut road accidents; and it would have a dramatic impact on the air pollution, which is currently the highest in the world for some noxious gases.

The news revealed that Oxford Street, by the beginning of January, has already breached its annual air pollution limit just four days into the New Year has reinforced this. Air pollution contributes to thousands of deaths in the capital each year. We simply cannot tackle this without taking polluting vehicles off the road.

In fact, the air pollution is so bad on Oxford Street that the European Court of Justice recently ruled that the Government must take action to reduce it from these harmful levels. It’s time we had a Mayor that is prepared to sort out the real problems facing London and air pollution is one of them.

Oxford Street is a nightmare and must be pedestrianised. Buses barely travel faster than pedestrians along the road making bus or taxi travel redundant. I would also ensure free Oyster travel on the tube between Tottenham Court Road and Marble Arch so that commuters are still able to travel through the area.

Making London more liveable is at the heart of my vision for our amazing city. This covers a huge number of areas, from housing to transport; communities to crime. However, we can start by reclaiming one of our city’s iconic streets for ourselves and the millions of tourists that enjoy the West End each year.
