My biggest concern is security and keeping Londoners safe.

Britain cannot compete with China or Taiwan on price; we compete on skills, on arts and culture.

Raising the congestion charge won't necessarily make a difference. Rather than increasing the amount you pay in congestion charge, we should be thinking about an ultra low emission zone. We should penalise those cars who are the biggest polluters and reward cars that don't, like electric cars.

I would use the power of procurement, I would say if you want to do business with the mayor of London, you must pay your staff a London Living Wage.

You cannot live in the best city in the world and have people living on the streets.

I am the only candidate for mayor of London with the experience of being a transport minister.

There is one school of thought that says Mayors should cut ribbons, be funny and be a buffoon. The other school of thought is that we can do more. Scotland is getting more powers. Wales is getting more powers. Greater Manchester. London needs more powers.
