As a result of Brexit, Great Britain will have more control over the negotiation of their own trade agreements and immigration policies, and they will also be able to redeploy the eventual savings of their EU membership to other areas of their economy that they feel would be more beneficial to their own citizens.
According to BBC.com, approximately 28% of what is produced in Great Britain is sold abroad. Interestingly, while about half of this overseas trade in the United Kingdom (UK) is conducted with the EU, England imports more overall than it exports to the EU.
