How is it having more control if there is double the immigration as there would be under an Australian style points system?

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

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

London has always been open to trade, people, ideas. We have to keep that. I want to compete not just with New York, Paris, Berlin... the ten fastest growing cities in the world are in China. How do we compete with them? We have to attract investment and we have to compete on skills.

London had always been different. There is the old saying that Britain is ten years behind America, and the country as a whole is ten years behind London. If you have a Mayor of London working for jobs and growth and strong businesses, that is going to create opportunities for businesses and people in Burnley or Hull and places all over the UK.

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.

There is no doubt that we need to manage migration better.Migrants are always getting the blame for politicians.
