The decision to trigger Article 50 is in the hands of the next prime minister. If that is me, I will make a judgement as to when is right for Britain, and I won't be hurried or hassled by anyone into pressing that button or triggering that article until I believe it is right for this country.
My view is that those challenges will be easier to meet, those risks will be less if we vote to leave because we will have control of the economic levers; we will have control over money we send to the European Union. We will have control over our own laws, and as a result, we will be able to deal with whatever the world throws at us.
