Leaving the EU will damage our economy. The only question is just how badly. Many of the people who will be affected (like the Nissan employees) voted brexit. I know posters on here will say they were not influenced by the lies of the brexit campaign but undoubtedly many did really believe that the NHS would get £350m and that Turkey was about to join the EU.
Given that the leave campaign was corrupt and never mentioned any details about what brexit actually meant I think it is now necessary to have another referendum to resolve matters.
