I absolutely understand. Some people have said to me that we should not have triggered article 50 when we did. I think it was important that we triggered it when we did. We took time to prepare, but then triggered it precisely in order to get this process into place. My right hon. Friend will know the process within article 50 is for two years. That is why we will leave the EU on 29 March 2019. What we are working to ensure is that we get the future relationship in place at the end of that implementation period, an implementation period that I believe was right and necessary to negotiate to ensure that for both citizens and businesses there were not two cliff-edges in the changed relationship with the EU, but we have a smooth and orderly withdrawal and movement into the future partnership.
