Brexit is a democratic choice that has been made by the people. The many questions of how well informed the people were to make this choice is irrelevant. A new referendum is a test of the REAL impact of Brexit following the departure. A test of fact rather than a test based on speculation or fear.

There are so many arguments, debates and opinions on Brexit. Probably there is more now than before and during the referendum. Brexit should be accepted without delay - the delay is costing the nation and business money, that should be used for more important things. We will only know the impact AFTER the event - everything else is speculation based on opinions. This new referendum will allow the people to review their decision. If it is working, great, if not, then change. Everything changes.
