My biggest concern is security and keeping Londoners safe.

We need to make it safe to cycle across London. Why not pedestrianise parts of London like Oxford Street and Parliament Square? I intend to plant 200 million trees across London in my term as mayor.

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

How is it having more control if there are businesses from China, India, America choosing Germany and France over London?

I am backing Remain for a very simple reason: it is the best way of protecting jobs, wages and rights for working people.

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.

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